Chiral synthesis of (–)-mesembranol starting from D-glucose
Abstract
The chiral synthesis of the Sceletium alkaloid, (–)-mesembranol 1 is described; the cyclohexane ring in 1 is prepared in an optically active form from D-glucose using Ferrier's carbocyclisation reaction and the perhydroindole skeleton is effectively constructed by an intramolecular aminomercuration reaction.
