title: Total synthesis of fostriecin: via a regio- and stereoselective polyene hydration, oxidation, and hydroboration sequence.
abstract: 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-closing metathesis reaction. 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 with a regio- and stereoselective asymmetric hydration/oxidation sequence.
