Total synthesis of (+)-monocerin via tandem dihydroxylation-SN2 cyclization and a copper mediated tandem cyanation–lactonization approach

Abstract

A simple and novel synthesis of (+)-monocerin was achieved in 15 steps and 15.5% overall yield from 3-buten-1-ol employing hydrolytic kinetic resolution, Julia olefination, intramolecular tandem Sharpless asymmetric dihydroxylation-S_N2 cyclization and a novel copper mediated tandem cyanation–cyclization as the key steps.
