Abstract

We studied the behaviour of bicyclic mesoionic compounds derived from the cyclodehydration of cyclic N-acyl-α-aminoacids 1-4 with N- (phenylmethylene)benzenesulfonamide 5. The reaction affords spirocyclic β- lactams and/or imidazo-condensed products (the 1,3-dipolar cycloaddition adducts) depending on the experimental conditions and on the nature of the substituent R on the mesoionic ring.
