Abstract
A novel radical [1,3]-nitrogen shift catalyzed by copper diacetate under an oxygen atmosphere (1 atm) has been developed for the construction of a diverse range of indole derivatives from α,α-disubstituted benzylamine. In this reaction, oxygen was used as a clean terminal oxidant, and water was produced as the only by-product. Five inert bonds were cleaved, and two C-N bonds and one C-C double bond were constructed in one pot during this transformation. This unique method demonstrated broad application protential for the late-stage modification of biologically active natural products and drugs. Mechanistic investigations indicate that a unique 4-exo-trig cyclization of an aminyl radical onto a phenyl ring is involved in the catalytic cycle.

Abstract
A convenient synthesis of 1-aryl-1H-1,2,3-triazoles through the one pot cascade reactions of alkynes with aliphatic azides and allenic ketones is presented. Mechanically, the formation of the title compounds involves a copper-catalyzed cycloaddition of alkyne with 4-azido-3-oxobutanoate to give 3-oxo-4-(1H-1,2,3-triazol-1-yl)butanoate as a key intermediate followed by its [3 + 3] annulation with allenic ketone through Michael addition and intramolecular condensation. A comparison study showed that using aliphatic azide as the substrate is superior to aromatic azide in terms of efficiency and selectivity. Furthermore, the 1-aryl-1H-1,2,3-triazoles bearing a 2'-bromophenyl unit attached on the 2-position of the in situ formed aryl ring obtained herein could be readily transformed into the biologically and pharmaceutically valuable tretracyclic triazolophenanthridines with good yields via a Pd-catalyzed C-H arylation.

Abstract
Full details of the total synthesis of the Schisandraceae nortriterpenoid natural product rubriflordilactone A are reported. Palladium- and cobalt-catalyzed polycyclizations were employed as key strategies to construct the central pentasubstituted arene from bromoendiyne and triyne precursors. This required the independent assembly of two AB ring aldehydes for combination with a common diyne component. A number of model systems were explored to investigate these two methodologies, and also to establish routes for the installation of the challenging benzopyran and butenolide rings.

Abstract
Pericyclic reactions are among the most powerful synthetic transformations to make multiple regioselective and stereoselective carbon-carbon bonds1. These reactions have been widely applied for the synthesis of biologically active complex natural products containing contiguous stereogenic carbon centers2–6. Despite the prominence of pericyclic reactions in total synthesis, only three naturally existing enzymatic examples, intramolecular Diels-Alder (IMDA) reaction7, Cope8 and Claisen rearrangements9, have been characterized. Here, we report the discovery of a S-adenosyl-L-methionine (SAM) dependent enzyme LepI that can catalyse stereoselective dehydration, bifurcating IMDA/hetero-DA (HDA) reactions via an ambimodal transition state, and a [3,3]-sigmatropic retro-Claisen rearrangement leading to the formation of dihydopyran core in the fungal natural product leporin10. Combined in vitro enzymatic characterization and computational studies provide evidence and mechanistic insight about how the O-methyltransferase-like protein LepI regulates the bifurcating biosynthetic reaction pathways (“direct” HDA and “byproduct recycle” IMDA/retro-Claisen reaction pathways) by utilizing SAM as the cofactor in order to converge to the desired biosynthetic end product. This work highlights that LepI is the first example of an enzyme catalysing a (SAM-dependent) retro-Claisen rearrangement. We suggest that more pericyclic biosynthetic enzymatic transformations are yet to be discovered in the intriguing enzyme toolboxes in Nature11, and propose an ever expanding role of the versatile cofactor SAM in enzyme catalysis.

A manganese(I) complex catalyzed the first example of directed C-H allylation with allenes, setting the stage for an in situ Povarov cyclization catalyzed by silver(I). The reaction proceeds with high bond-forming efficiency (three C-C bonds), broad substrate scope, high regio- and stereoselectivity, and 100 % atom economy.

Abstract
Metathesis reactions is firmly established as a valuable synthetic tool in organic chemistry, clearly comparable with the venerable Diels-Alder and Wittig reactions and, more recently, with the metal-catalyzed cross-coupling reactions. Metathesis reactions can be considered as a fascinating synthetic methodology, allowing different variants regarding substrate (alkene and alkyne metathesis) and type of metathetical reactions. On the other hand, tandem metathesis reactions such Ring Rearrangement Metathesis (RRM) and the coupling of metathesis reaction with other reactions of alkenes such as Diels-Alder or Heck reactions, makes metathesis one of the most powerful and reliable synthetic procedure.In particular, Ring-Rearrangement Metathesis (RRM) refers to the combination of several metathesis transformations into a domino process such as ring-opening metathesis (ROM)/ring-closing metathesis (RCM) and ROM-cross metathesis (CM) in a one-pot operation. RRM delivers complex frameworks that are difficult to assemble by conventional methods constitutingan atom economic process. RRM is applicable to mono- and polycyclic systems of varying ring sizes such as cyclopropene, cyclobutene, cyclopentene, cyclohexene, pyran systems, bicyclo[2.2.1]heptene derivatives, bicyclo[2.2.2]octene derivatives, bicyclo[3.2.1]octene derivatives and bicyclo[3.2.1]octene derivatives.In this review our attention has focused on the RRM reactions in 7-oxabicyclo[2.2.1]heptene derivatives and on their application in the synthesis of natural products or significant subunits of them.

Abstract
Natural products have been an excellent and abundant source of therapeutics for many decades. To expand on their success, and explore areas of chemical space not covered by biosynthesis, the synthesis of natural product-inspired compound collections has emerged as a viable strategy. Herein we describe the principles behind biology-oriented synthesis and related approaches, the requirements for development of novel chemistry and how phenotypic screens are a very fruitful way to explore the bioactivity of compounds made using these approaches. Finally, we summarize state-of-the-art techniques to identify the biological targets of any hits identified.

Abstract
An enantioselective synthesis of S-(-)-5,6-dihydrocanthin-4-ones via a triple cooperative catalysis-mediated domino reaction having a broad substrate scope is reported. The reaction between substituted 1-formyl-9H-β-carbolines and terminal alkynes in the presence of catalytic amounts of Jorgensen-Hayashi catalyst, copper iodide, and Hunig base proceeded via a multicascade route, affording the title compounds in good yields and excellent ees with interesting mechanistic features. These compounds were assessed for in vitro antiplasmodial activity against P. falciparum strains. Additionally, 5,6-dihydrocanthin-4-ones are demonstrated to be a versatile precursor to different fused β-carboline derivatives via simple synthetic transformations.

Abstract
![]()
The
gold(I)-catalyzed intramolecular reaction of allenes with oxoalkenes
leads to bicyclo[6.3.0]undecane ring systems, although in the case
of terminally disubstituted allenes, seven-membered rings are formed.
The related intermolecular addition of aldehydes to allenenes also
gives seven-membered rings.
