4-MeOC6H4), cyclized with dearomatization to give Me dienylethers, e.g. II, which were hydrolyzed with dil. HCl to give single stereo- and regioisomers of pyrrolidine-fused cyclohexenones, e.g. III. The bicyclic enones are versatile synthetic intermediates which undergo transformations such as stereoselective redn. and conjugate addn., regioselective Baeyer-Villiger oxidn., bromination and hydrogenation
