Stereoselective synthesis of amphidinolide T1.

A highly stereoselective total synthesis of amphidinolide T1 is achieved using Sharpless asymmetric epoxidation, base-induced epoxide opening, radical cyclization, diastereoselective reduction followed by allylation, Evans methylation, base-induced reductive elimination, umpolung reaction, chemoselective oxidation, and regioselective macrolactonization.
