The present invention discloses organocatalytic process for asymmetric synthesis of highly enantioselective decanolide compounds in high yield with >99% ee. Further, the present invention disclose cost effective, improved organocatalytic process for asymmetric synthesis of highly enantioselective decanolides compounds from non-chiral, cheap, easily available raw materials.
The first totalsynthesis of a 10-membered macrolide, stagonolide E is described from readily available 4-penten-1-ol. The synthetic strategy involves Jacobsen’s kinetic resolution, Sharpless epoxidation, Stille–Gennari, and Yamaguchi lactonization as key reactions.
