Direct catalytic asymmetric synthesis of α-chiral bicyclo[1.1.1]pentanes

Abstract

Bicyclo[1.1.1]pentanes (BCPs) are important motifs in contemporary drug design, however, approaches to BCPs featuring adjacent stereocenters are rather limited. Here, the authors report a photo- and organocatalyzed asymmetric addition of simple aldehydes to [1.1.1]propellane to generate enantioenriched α-chiral BCPs.
