Olefin cross-metathesis based approach for the stereoselective total synthesis of (+)-cardiobutanolide

Olefin cross-metathesis approach to (+)-cardiobutanolide has been achieved starting from d-mannitol utilizing Sharpless kinetic resolution and Sharpless asymmetric dihydroxylation.

A stereoselective total synthesis of (+)-cardibutanolide is reported.
