available from secondary propargylic alcohols via a two-step sequence involving highly regio- and stereoselective Pd(0)-catalyzed hydrostannation followed by mild oxidation (TPAP). The methodology has been applied to the synthesis of enantiomerically pure enone 12 which is a keyintermediate for the total synthesis of zoanthamine, a structurally complex marine natural product.
