A short, efficient and novel approach for multifunctionalized γ-butyrolactone paraconic acids and its application to the total synthesis of (+)-nephrosteranic acid from readily available PMB (R)-glycidyl ether as a starting material are described.
A short, efficient and novel enantioselective general approach for the synthesis of muscarine alkaloid and its application to the asymmetric synthesis of epi‐muscarine from readily available (R)‐PMB glycidyl ether as starting material is described. Key transformations include Sharpless asymmetric dihydroxylation (AD), regioselective epoxide ring opening and intramolecular SN2 cyclization.
An efficient enantioselective approach of Sacubitril 1 (a NEP inhibitor) which is used as a combination drug with Valsartan to treat heart failure, is described. The synthesis features the Evan's asymmetric alkylation, Sharpless asymmetric diydroxylation (AD) and Heck coupling reactions as key steps.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
