Full details of the synthesis of the fullyelaborated aziridino[1,2-a]pyrrolidine substructure 2 of the antitumor agents azinomycins A and B are reported. Stereoselective bromination of dehydroamino acid 4 provided control of olefin configuration in the final product, as a consequence of a stereospecific cyclization of aziridine 3 onto the proximal β-bromoacrylate, which effected pyrrolidine ring introduction
