Synthesis of migrastatin and its macrolide core

Migrastatin and its macrolactone subunit are potent antimetastatic agents. Both were synthesized by using a ring-closing metathesis (RCM) to establish the macrolactone core, and the control of the (Z)-trisubstituted double bond at C11-C12 was achieved by using a Still-Gennari olefination.
