Total Synthesis of Rhoiptelol B
Publication History
Publication Date:
28 October 2010 (online)

Abstract
A simple and efficient total synthesis of rhoiptelol B, isolated from the the leaves and fruits of Rhoiptelea chiliantha, is achieved using Sharpless asymmetric epoxidation, 1,3-anti-chiral allylation, olefin cross-metathesis, Sharpless asymmetric dihydroxylation, and ferric chloride catalyzed intramolecular SN2 cyclization as the key steps.
Key words
rhoiptelol B - Sharpless asymmetric epoxidation - allylation - cross-metathesis - diarylheptanoids
