Macrolides remain as a good synthetic targets due to their structural diversities, biological activities and important medicinal properties. (+) Migrastatin (1), a novel macrolide natural product displays a significant inhibition on the migration of human tumor cells. The synthesis of the 14-membered macrolide core (3) of migrastatin envisaged the preparation of key intermediate (2) via a diastereoselective aldol condensation and exclusive (Z)-olefination. Yamaguchi esterification of key intermediate (2) followed by ring-closing metathesis (RCM) produced the macrolide 3.
