Stereoselective construction of ethyl (13E)-trifluoromethylretinoate was achieved through two successive Stille reactions. The coupling of (E)-1,2-bis(tributylstannyl)ethene and ethyl (Z)-4,4,4-trifluoro-3-iodobut-2-enoate was performed first and followed by iododestannylation. The second step involved another vinyltin which was synthetised by stannylmetallation of the Nigishi dienyne 4c derived from
