Stereoselective construction of 3-trifluoromethyl conjugated dienoates or enynoates was achieved from ethyl (Z)-4,4,4-trifluoro-3-iodobutenoate and alkenyltin or alkynyltin reagents through the Stille reaction. Reduction of ethyl 3-trifluoromethyldienoates using DIBAL-H selectively afforded allylic alcohols.
