A novel method for the stereoselective synthesis of all-E-, 13Z- and 9Z-retionic acid esters was developed by palladium-catalyzed cross coupling reactions of tetraenyl stannanes with E- or Z-vinyl triflates in good yields. Applying this methodology, 13-substituted all-E- and 9Z-retionic acids were prepared in satisfactory yields.
