systematically explored a transannular Michael reaction cascade for stereoselective synthesis of polycyclic systems. Both E,Z- and E,E-1,7-bis-enones in the form of 14-membered macrocyclic lactones underwent transannularcyclization to give polycyclic products with high efficiency and excellent diastereoselectivity. In contrast, Z,E- and Z,Z-macrocyclic lactones did not cyclize under similar reaction
