Abstract
Since the beginning of this century, p-toluenesulfonic acid (p-TSA) catalysed organic transformations have been an active area of research for developing efficient synthetic methodologies. Often, catalysis using p-TSA is associated with many advantages, such as operational simplicity, high selectivity, excellent yields, and ease of product isolation, which make organic synthesis convenient and versatile. Notably, p-TSA is a non-toxic, commercially available, inexpensive solid organic compound that is soluble in water, alcohols, and other polar organic solvents. p-TSA is a strong acid compared to many protic or mineral acids and its high acidity helps activate different organic functional groups. p-TSA-promoted conversions are fast, have a high atom and pot economy, and feature a multiple bond-forming index. Therefore, the utilization of p-TSA enables the synthesis of many important structural scaffolds without any hazardous metals, making it desirable in numerous applications of sustainable and green chemistry. Recently, this emerging area of research has become one of the pillars of synthetic organic chemistry to synthesise biologically relevant, complex carbocycles and heterocycles. This study provides a comprehensive summary of methods, applications, and mechanistic insights into p-TSA-catalysed organic transformations, covering the literature reports that have appeared since 2012.

Abstract
An efficient synthesis of (+)-peniciketal B has been accomplished in 15 steps from the commercially available materials atraric acid, acryloyl chloride, and (+)-homoallylic alcohol. A convergent synthetic approach that is quite concise for constructing either "hemisphere" of (+)-peniciketal B with a common intermediate is employed that relies on a cascade intermolecular FeCl3-mediated "inner sphere" Michael-type reaction/double cyclization of an α,β-unsaturated ketone and substituted phenol to build the benzo-fused 2,8-dioxabicyclo[3.3.1]nonane with excellent diastereoselectivity. The generality of the transformation was also demonstrated by the broad scope of substrates that would be potential candidates for natural product synthesis and medicinal chemistry. Benzannulated [6,6]spiroketal was installed by a late-stage acid-catalyzed spiroketalization.

Lactate dehydrogenase A inhibitors with a 2,8-dioxabicyclo[3.3.1]nonane scaffold: A contribution to molecular therapies for primary hyperoxalurias. Bioorg Chem 2022; 129:106127. [PMID: 36113265 DOI: 10.1016/j.bioorg.2022.106127] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 05/22/2022] [Accepted: 09/02/2022] [Indexed: 12/12/2022]
Abstract
Human lactate dehydrogenase A (hLDHA) is one of the main enzymes involved in the pathway of oxalate synthesis in human liver and seems to contribute to the pathogenesis of disorders with endogenous oxalate overproduction, such as primary hyperoxaluria (PH), a rare life-threatening genetic disease. Recent published results on the knockdown of LDHA gene expression as a safe strategy to ameliorate oxalate build-up in PH patients are encouraging for an approach of hLDHA inhibition by small molecules as a potential pharmacological treatment. Thus, we now report on the synthesis and hLDHA inhibitory activity of a new family of compounds with 2,8-dioxabicyclo[3.3.1]nonane core (23-42), a series of twenty analogues to A-type proanthocyanidin natural products. Nine of them (25-27, 29-34) have shown IC50 values in the range of 8.7-26.7 µM, based on a UV spectrophotometric assay, where the hLDHA inhibition is measured according to the decrease in absorbance of the cofactor β-NADH (340 nm). Compounds 25, 29, and 31 were the most active hLDHA inhibitors. In addition, the inhibitory activities of those nine compounds against the hLDHB isoform were also evaluated, finding that all of them were more selective inhibitors of hLDHA versus hLDHB. Among them, compounds 32 and 34 showed the highest selectivity. Moreover, the most active hLDHA inhibitors (25, 29, 31) were evaluated for their ability to decrease the oxalate production by hyperoxaluric mouse hepatocytes (PH1, PH2 and PH3) in vitro, and the relative oxalate output at 24 h was 16% and 19 % for compounds 25 and 31, respectively, in Hoga1-/- mouse primary hepatocyte cells (a model for PH3). These values improve those of the reference compound used (stiripentol). Compounds 25 and 31 have in common the presence of two hydroxyl groups at rings B and D and an electron-withdrawing group (NO2 or Br) at ring A, pointing to the structural features to be taken into account in future structural optimization.

Abstract
A one-pot method for the selective synthesis of two isomers 4H-chromene and 2,8-dioxabicyclo[3.3.1]nonane derivatives was developed without a catalyst and using EtOH/H2O (4:1, v/v) as the solvent. The reaction was conducted under mild conditions, with forming multiple chemical bonds in one pot and high atom economy, and only a stoichiometric amount of H2O is produced as the byproduct. Its selectivity was controlled by thermodynamics and kinetics, and the reasons for the transformation of the two structures are also discussed.

Abstract
Background:
Since the discovery of metal-free catalysts or organocatalysts about twenty
years ago, a number of small molecules with different structures have been used to accelerate organic
transformations. With the development of environmental awareness, to obtain highly efficient
scaffolds, scientists have directed their studies towards synthetic methodologies that minimize
or preferably eliminate the formation of waste, avoid toxic solvents and reagents and use renewable
starting materials as far as possible.
Methods:
In this connection, the organocatalytic reactions providing efficiency and selectivity for
most of the transformations have become an endless topic in organic chemistry since several advantages
from both practical and environmental standpoints. Organocatalysts contributing to the transformation
of reactants into products with the least possible waste production, have been serving the
concept of green chemistry.
Results and Conclusion:
Organocatalysts have been classified based on their binding capacity to
the substrate with covalent or noncovalent interactions involving hydrogen bonding and electrostatic
interaction. Diverse types of small organic compounds including proline and its derivatives,
phase-transfer catalysts, (thio)urease, phosphoric acids, sulfones, N-oxides, guanidines, cinchona
derivatives, aminoindanol, and amino acids have been utilized as hydrogen bonding organocatalysts
in different chemical transformations.

Abstract
Proanthocyanidins (PACs) are oligomers or polymers composed of units of flavanols. A-type PACs are a subclass of PACs characterized by the presence of at least a double linkage between two consecutive monomers of flavanol. These A-type PACs are found in some fruits and spices and possess potential health benefits as a result of their interesting biological activities, and consequently, their isolation and synthesis have given rise to great interest in the past. This review summarizes the synthetic efforts made to obtain both naturally occurring A-type PACs and their structurally simplified analogues. Most of the synthetic protocols reported involve the addition of a π-nucleophilic molecule over a molecule with two electrophilic carbons, such as a chalcone, a flavylium salt, or a flavanol derivative, among others. Synthesis of A-type PACs remains an issue at a very early stage of development compared to that of PACs with single linkages between monomers (B-type PACs), but the advances that are taking place in the last few years point to a significant development of the subject in the near future.

Abstract
Diverse naphtho[1,2-b]furan-3-carboxamide derivatives 12a-12q were synthesized in high yield via the novel Re2O7-catalyzed formal [3 + 2] cycloaddition of 1,4-naphthoquinones with β-ketoamides as the key step. This methodology offers several advantages, such as environmentally benign character, the use of a mild catalyst, high yields, and ease of handling. The synthesized compounds were screened for their tyrosinase inhibitory, antioxidant, and antibacterial activities. The results showed that compound 12c exhibited excellent tyrosinase inhibitory activity with an IC50 of 13.48 μg/mL, which is comparable to that of kojic acid (IC50 = 19.45 μg/mL). Compounds 12a, 12b, and 12i displayed moderate antioxidant activities in a DPPH assay. Compound 12m showed good activity against S. aureus (MIC = 16 μg/mL), and compound 12p was found to be active against E. coli (MIC = 16 μg/mL).
