The aza-Prins reaction of 6,7-dimethoxy-3-vinyl-1,2,3,4-tetrahydroquinoline (1) with 1,2-dicarbonyl compounds proceeded smoothly in the presence HCl, and corresponding tricyclic benzazocines were isolated yields 20–86%. a stereoselective manner, formation 2,4-trans isomer was observed. 1 an enantiopure ketoester gave benzazocine as mixture diastereomers. diastereomers easily separated converted to benzazocines. synthesis spirooxindole derivatives achieved by isatin derivatives.
