Abstract

A highly convergent, stereoselective total synthesis of a ten-membered lactone, stagonolide G, is described. Epoxide ring-opening with vinyl Grignard, Yamaguchi esterification and ring-closing metathesis are the key steps involved in the present approach. d-Mannitol was used as a chiral pool material for the construction of both of the key fragments - the olefinic acid and the olefinic alcohol moieties.
