Zinc Chloride Catalyzed Ring Opening of N-Arylsulfonyl Aziridines by Thioamides: A New Approach to the Synthesis of Amidines
摘要:
The first zinc chloride catalyzed ring opening of N-arylsulfonyl aziridines by thioamides is described. Various thioamides were reacted with N-arylsulfonyl aziridines in the presence of a catalytic amount of dry zinc chloride to provide the corresponding N-arylsulfonyl amidine derivatives with good to excellent yields.
