Stereoselective synthesis of (+)-diplodialides-B, C and a formal synthesis of (+)-diplodialide-A by ring-closing metathesis approach
摘要:
Stereoselective synthesis of diplodialides-B and C and the formal synthesis of diplodialide-A are reported. A combination of Jacobsen's hydrolytic kinetic resolution and Sharpless epoxidation is used for the creation of two stereogenic centers, while a ring-closing metathesis strategy was used for the construction of the lactone ring.

A simple and efficient stereoselective synthesis of the C12-C24 fragment of the natural product macrolactin-A was achieved from D-glucose as the starting material and with use of the Wittig and modifiedJuliaolefinationreactions as key steps.
