A total synthesis of the fostriecin has been achieved in 24 steps from enyne 11. The lactone moiety was installed by a Leighton allylation and Grubbs ring-closingmetathesisreaction. The highly reactive Z,Z,E-triene moiety was installed via a late-stage Suzuki−Miyaura cross-coupling of a remarkably stable Z-vinyl boronate. The relative and absolute stereocenters of the C-8,9,11 triol were generated
