Abstract

Abstract A new diastereoselective pathway for the total synthesis of (+)-dexoxadrol, first asymmetric synthesis of (−)-epi-dexoxadrol and formal synthesis of conhydrine and (+)- lentiginosine is presented using commercially available (−)-pipecolinic acid. The key reactions utilized are Sharpless asymmetric dihydroxylation and Wittig reaction. The paper further describes the study of effect of protecting groups on dihydroxylation of a terminal ...
