Abstract
The carbon skeleton of any organic molecule serves as the foundation for its three-dimensional structure, playing a pivotal role in determining its physical and biological properties1. As such, taxane diterpenes are one of the most well-known natural product families, primarily owing to the success of their most prominent compound, paclitaxel, an effective anticancer therapeutic for more than 25 years2-6. In contrast to classical taxanes, the bioactivity of cyclotaxanes (also referred to as complex taxanes) remains significantly underexplored. The carbon skeletons of these two groups of taxanes differ significantly, and so would typically their own distinct synthetic approaches. Here we report a versatile synthetic strategy based on the interconversion of complex molecular frameworks, providing general access to the wider taxane diterpene family. A range of classical and cyclotaxane frameworks was prepared including, among others, the total syntheses of taxinine K (2), canataxapropellane (5) and dipropellane C from a single advanced intermediate. The synthetic approach deliberately eschews biomimicry, emphasizing instead the power of stereoelectronic control in orchestrating the interconversion of polycyclic frameworks.

Abstract
With the growing significance of green chemistry in organic synthesis, electrochemical oxidation has seen rapid development. Compounds undergo oxidation-reduction reactions through electron transfer at the electrode surface. This article proposes the use of electrochemical methods to achieve cleavage of the benzyl C-N bond. This method selectively oxidatively cleaves the C-N bond without the need for metal catalysts or external oxidants. Additionally, primary, secondary, and tertiary amines exhibit good adaptability under these conditions, utilizing water as the sole source of oxygen.

Abstract
A palladium-catalyzed Heck reaction between 2-oxyacrylates and aryl bromides was developed, where DavePhos was a unique ligand that efficiently promoted the reaction. The products, 2-oxycinnamates, served as excellent precursors, providing synthetically useful monoaryl pyruvates or ortho ester-protected monoaryl pyruvates depending on the nature of the 2-oxy group. The formation of such ortho esters via alkoxide addition is novel, and computational studies identified a plausible mechanism with an oxyallyl zwitterion as the key intermediate.

Abstract
Biomimetic oxidation of primary amines to carboxylic acids has been developed where the copper-containing amine oxidase (CuAO)-like o-NQ-catalyzed aerobic oxidation was combined with the aldehyde dehydrogenase (ALDH)-like TBHP-mediated imine oxidation protocol. Notably, the current tandem oxidation strategy provides a new mechanistic insight into the imine intermediate and the seemingly simple TBHP-mediated oxidation pathways of imines. The developed metal-free amine oxidation protocol allows the use of molecular oxygen and TBHP, safe forms of oxidant that may appeal to the industrial application.

Abstract
While primary aliphatic amines are ubiquitous in natural products, they are traditionally considered inert to substitution chemistry. This review highlights historical and recent advances in the field of aliphatic deamination chemistry which demonstrate these moieties can be harnessed as valuable C(sp3) synthons. Cross-coupling and photocatalyzed transformations proceeding through polar and radical mechanisms are compared with oxidative deamination and other transition metal catalyzed reactions.

Abstract
Selective oxidative deamination has long been considered to be an important but challenging transformation, although it is a common critical process in the metabolism of bioactive amino compounds. Most of the synthetic methods developed so far rely on the use of stoichiometric amounts of strong and toxic oxidants. Here we present a green and efficient method for oxidative deamination, using water as the oxidant, catalyzed by a ruthenium pincer complex. This unprecedented reaction protocol liberates hydrogen gas and avoids the use of sacrificial oxidants. A wide variety of primary amines are selectively transformed to carboxylates or ketones in good to high yields. It is noteworthy that mechanistic experiments and DFT calculations indicate that in addition to serving as the oxidant, water also plays an important role in assisting the hydrogen liberation steps involved in amine dehydrogenation.

Abstract
Among defensive alkaloids isolated from ladybugs, the heterodimeric member chilocorine C possesses an alluring monomeric unit that combines quinolizidine and indolizidine substructures. Indeed, the overall stereochemical disposition of its ring fusions is distinct from those of related natural products. Herein we show that a carefully orchestrated sequence with several chemoselective transformations, including a designed cascade that accomplishes nine distinct chemical reactions in one-pot, can smoothly forge that domain and ultimately enable a 15-step, 11-pot enantiospecific synthesis of the natural product. Mechanistic studies, density functional theory calculations, and the delineation of several other unsuccessful approaches highlight its unique elements.

Abstract
We report a novel approach to the classical natural product quinine that is based on two stereoselective key steps, namely a C-H activation and an aldol reaction, to unite the two heterocyclic moieties of the target molecule. This straightforward and flexible strategy enables a concise synthesis of natural (-)-quinine, the first synthesis of unnatural (+)-quinine, and also provides access to unprecedented C3-aryl analogues, which were prepared in only six steps. We additionally demonstrate that these structural analogues exhibit improved antimalarial activity compared with (-)-quinine both in vitro and in mice infected with Plasmodium berghei.

Abstract
A new metal-free protocol for promoting oxidation of amines in aqueous-organic medium was developed. NaIO4 and TEMPO as the catalyst emerged as the most efficient and selective system for oxidation of differently substituted benzyl amines to the corresponding benzaldehydes without overoxidation. Unsymmetrical secondary amines underwent selective oxidation only at the benzylic position thus realising an oxidative deprotection of a benzylic group with an easy amine recovery.

Abstract
A highly efficient metal free approach for the oxidation of primary and secondary amines to their corresponding aldehydes and ketones using PhI(OAc)2 in combination with a catalytic amount of TEMPO as an oxidizing agent is described. This protocol is rapid and provides diverse products under milder reaction conditions in excellent yields. In addition, the mechanistic study is well demonstrated by spectroscopic methods. A highly efficient, metal free rapid protocol studied mechanistically the oxidation of primary and secondary amines to their corresponding carbonyl compounds using PhI(OAc)2 and catalytic TEMPO to provide diverse products in excellent yields.![]()

Abstract
Nitrogen heteroarenes form an important class of compounds which can be found in natural products, synthetic drugs, building blocks etc. Among the diverse strategies that were developed for the synthesis of nitrogen heterocycles, oxidative dehydrogenation is extremely effective. This review discusses various oxidative dehydrogenation strategies of C-C and C-N bonds to generate nitrogen heteroarenes from their corresponding heterocyclic substrates. The strategies are categorized under stoichiometric and catalytic usage of reagents that facilitate such transformations. The application of these strategies in the synthesis of nitrogen heteroarene natural products and synthetic drug intermediates are also discussed. We hope this review will arouse sufficient interest among the scientific community to further advance the application of oxidative dehydrogenation in the synthesis of nitrogen heteroarenes.

Abstract
Copper amine oxidases are a family of enzymes with quinone cofactors that oxidize primary amines to aldehydes. The native mechanism proceeds via an iminoquinone intermediate that promotes high selectivity for reactions with primary amines, thereby constraining the scope of potential biomimetic synthetic applications. Here we report a novel bioinspired quinone catalyst system consisting of 1,10-phenanthroline-5,6-dione/ZnI2 that bypasses these constraints via an abiological pathway involving a hemiaminal intermediate. Efficient aerobic dehydrogenation of non-native secondary amine substrates, including pharmaceutically relevant nitrogen heterocycles, is demonstrated. The ZnI2 cocatalyst activates the quinone toward amine oxidation and provides a source of iodide, which plays an important redox-mediator role to promote aerobic catalytic turnover. These findings provide a valuable foundation for broader development of aerobic oxidation reactions employing quinone-based catalysts.

Abstract
This paper reviews recent electrochemical studies of the copper complexes of prion protein (PrP) and its related peptides, and correlates their redox behavior to chemical and biologically relevant reactions. Particular emphasis is placed on the difference in redox properties between copper in the octarepeat (OR) and the non-OR domains of PrP, as well as differences between the high and low copper occupancy states in the OR domain. Several discrepancies in literature concerning these differences are discussed and reconciled. The PrP copper complexes, in comparison to copper complexes of other amyloidogenic proteins/peptides, display a more diverse and richer redox chemistry. The specific protocols and caveats that need to be considered in studying the electrochemistry and redox reactions of copper complexes of PrP, PrP-derived peptides, and other related amyloidogenic proteins are summarized.

Abstract
Ascorbic acid (AscH(2)) and dihydronicotinamide adenine dinucleotide (NADH) are two very important natural redox cofactors, which can be used as hydride, electron, and hydrogen atom sources to take part in many important bioreduction processes in vivo. The differences of the two natural reducing agents as hydride, hydrogen atom, and electron donors in thermodynamics, kinetics, and mechanisms were examined by using 5,6-isopropylidene ascorbate (iAscH(-)) and β-D-glucopyranosyl-1,4-dihydronicotinamide acetate (GluNAH) as their models, respectively. The results show that the hydride-donating ability of iAscH(-) is smaller than that of GluNAH by 6.0 kcal/mol, but the electron-donating ability and hydrogen-donating ability of iAscH(-) are larger than those of GluNAH by 20.8 and 8.4 kcal/mol, respectively, which indicates that iAscH(-) is a good electron donor and a good hydrogen atom donor, but GluNAH is a good hydride donor. The kinetic intrinsic barrier energy of iAscH(-) to release hydride anion in acetonitrile is larger than that of GluNAH to release hydride anion in acetonitrile by 6.9 kcal/mol. The mechanisms of hydride transfer from iAscH(-) and GluNAH to phenylxanthium perchlorate (PhXn(+)), a well-known hydride acceptor, were examined, and the results show that hydride transfer from GluNAH adopted a one-step mechanism, but the hydride transfer from iAscH(-) adopted a two-step mechanism (e-H(•)). The thermodynamic relation charts (TRC) of the iAscH(-) family (including iAscH(-), iAscH(•), iAsc(•-), and iAsc) and of the GluNAH family (including GluNAH, GluNAH(•+), GluNA(•), and GluNA(+)) in acetonitrile were constructed as Molecule ID Cards of iAscH(-) and of GluNAH in acetonitrile. By using the Molecule ID Cards of iAscH(-) and GluNAH, the character chemical properties not only of iAscH(-) and GluNAH but also of the various reaction intermediates of iAscH(-) and GluNAH all have been quantitatively diagnosed and compared. It is clear that these comparisons of the thermodynamics, kinetics, and mechanisms between iAscH(-) and GluNAH as hydride and electron donors in acetonitrile should be quite important and valuable to diagnose and understand the different roles and functions of ascorbic acid and NADH as hydride, hydrogen atom, and electron sources in vivo.

Abstract
The prion protein (PrP) takes up 4-6 equiv of copper in its extended N-terminal domain, composed of the octarepeat (OR) segment (human sequence residues 60-91) and two mononuclear binding sites (at His96 and His111; also referred to as the non-OR region). The OR segment responds to specific copper concentrations by transitioning from a multi-His mode at low copper levels to a single-His, amide nitrogen mode at high levels (Chattopadhyay et al. J. Am. Chem. Soc. 2005, 127, 12647-12656). The specific function of PrP in healthy tissue is unclear, but numerous reports link copper uptake to a neuroprotective role that regulates cellular stress (Stevens, et al. PLoS Pathog.2009, 5 (4), e1000390). A current working hypothesis is that the high occupancy binding mode quenches copper's inherent redox cycling, thus, protecting against the production of reactive oxygen species from unregulated Fenton type reactions. Here, we directly test this hypothesis by performing detailed pH-dependent electrochemical measurements on both low and high occupancy copper binding modes. In contrast to the current belief, we find that the low occupancy mode completely quenches redox cycling, but high occupancy leads to the gentle production of hydrogen peroxide through a catalytic reduction of oxygen facilitated by the complex. These electrochemical findings are supported by independent kinetic measurements that probe for ascorbate usage and also peroxide production. Hydrogen peroxide production is also observed from a segment corresponding to the non-OR region. Collectively, these results overturn the current working hypothesis and suggest, instead, that the redox cycling of copper bound to PrP in the high occupancy mode is not quenched, but is regulated. The observed production of hydrogen peroxide suggests a mechanism that could explain PrP's putative role in cellular signaling.

Abstract
2',4'-Propylene-bridged thymidine (carba-ENA-T) and five 8'-Me/NH(2)/OH modified carba-ENA-T analogues have been prepared through intramolecular radical addition to C═N of the tethered oxime-ether. These carba-ENA nucleosides have been subsequently incorporated into 15mer oligodeoxynucleotides (AON), and their affinity toward cDNA and RNA, nuclease resistance, and RNase H recruitment capability have been investigated in comparison with those of the native and ENA counterparts. These carba-ENAs modified AONs are highly RNA-selective since all of them led to slight thermal stabilization effect for the AON:RNA duplex, but quite large destabilization effect for the AON:DNA duplex. It was found that different C8' substituents (at the bottom of the minor groove) on carba-ENA-T only led to rather small variation of thermal stability of the AON:RNA duplexes. We, however, observed that the parent carba-ENA-T modified AONs exhibited higher nucleolytic stability than those of the ENA-T modified counterparts. The nucleolytic stability of carba-ENA-T modified AONs can be further modulated by C8' substituent to variable extents depending on not only the chemical nature but also the stereochemical orientation of the C8' substituents: Thus, (1) 8'S-Me on carba-ENA increases the nucleolytic stability but 8'R-Me leads to a decreased effect; (2) 8'R-OH on carba-ENA had little, if any, effect on nuclease resistance but 8'S-OH resulted in significantly decreased nucleolytic stability; and (3) 8'-NH(2) substituted carba-ENA leads to obvious loss in the nuclease resistance. The RNA strand in all of the carba-ENA derivatives modified AON:RNA hybrid duplexes can be digested by RNase H1 with high efficiency, even at twice the rate of those of the native and ENA modified counterpart.
