synthesis of fostriecin is described, featuring sequential palladium-catalyzed Negishi cross couplings to form the C7−C8 bond and C8−methyl bond, followed by late-stage regio- and stereoselective dihydroxylation of C8−C9.

An enantioselectiveallylation of silyl-substituted acetylenic aldehydes by chiralphosphoricacid (CPA)/transition metal cooperative catalysis was developed. Enantioenriched homoallylic propargyl alcohols were obtained in good yields with excellent enantioselectivities (>99% ee) under mild conditions. Moreover, the shortest formal synthesis of fostriecin was achieved by the present enantioselective
