ADDITION OF α-HALOSULFINYL BARBANIONS TO IMINES. CONVENIENT PREPARATIONS OF SUBSTITUTED AZIRIDINES AND PYROLES

Article abstract of DOI:10.1246/cl.1984.969

α-Lithio-α-chloro and -α-fluoromethyl phenyl sulfoxides react with N-(benzylidene)anilines to give the corresponding aziridines in good yields.Pyrolyses of these compounds in the presence of dimethyl acetylenedicarboxylate result in substituted pyrroles in high yields.
