Abstract

The first stereoselective total synthesis of new natural amide alkaloids 1–3 have been achieved from commercially available starting materials. Wittig olefination, Sharpless asymmetric dihydroxylation, epoxidation, a trans regioselective opening of 2, 3-epoxy alcohol, Horner–Wadsworth–Emmons (HWE) olefination and amide coupling are the key steps. The amide alkaloids 1–3 are evaluated for their anticancer activity against colon ( ...
