Skeletal Rearrangements of Amides via Breaking Inert Bonds
Chemistry – A European Journal, Volume 31, Issue 25, May 5, 2025.This review highlights advances in amide skeletal rearrangement reactions over the past two decades, categorized by the initial bond cleavages: C─N bond cleavage, C─C bond cleavage, and C═O bond activation. It summarizes emerging strategies, mechanistic insights, and synthetic applications, providing a focused perspective on recent developments in this

ChemistryOpen, Volume 14, Issue 5, May 2025.A user‐friendly protocol for the synthesis 3‐substituted coumarin derivatives was developed using Friedel‐Crafts alkylation and ozonolysis as key steps. Deactivation of 3‐chymotrypsin like protease (3CLpro) enzyme using these coumarin derivatives were investigated to explored their potential as 3CLpro inhibitors for Covid‐19 Therapeutics.

Enantioselective Synthesis of (+)-Cephalostatin 1 [PDF]
, 2012 This Article describes an enantioselective synthesis of cephalostatin 1. Key steps of this synthesis are a unique methyl group selective allylic oxidation, directed C−H hydroxylation of a sterol at C12, Au(I)-catalyzed 5-endo-dig cyclization, and a ...

Rh(II) catalyzed efficient sigmatropic rearrangement reaction of pyridotriazoles and sulfides
Green Synthesis and CatalysisThe [2,3]- and [1,2]-sigmatropic rearrangement reactions between pyridotriazoles and sulfides catalyzed by rhodium(II) were investigated. The utilization of pyridotriazoles as the carbene precursors in this kind of reaction efficiently constructed the C ...

Three applications of path integrals: equilibrium and kinetic isotope effects, and the temperature dependence of the rate constant of the [1,5] sigmatropic hydrogen shift in (Z)-1,3-pentadiene [PDF]
, 2018 Recent experiments have confirmed the importance of nuclear quantum effects even in large biomolecules at physiological temperature. Here we describe how the path integral formalism can be used to describe rigorously the nuclear quantum effects on ...
