Synthesis of 2-Sulfanyl-4H-3,1-benzothiazine Derivatives by the Reaction of 2-(Bromomethyl)phenyl Isothiocyanates with Thiols
摘要:
The reaction of 2-(bromomethyl)phenyl isothiocyanates with thiols in the presence of triethylamine gave the corresponding 2-sulfanyl-4H-3,1-benzothiazines. The procedure was successfully applied to the preparation of 1,omega-bis[(4H-3,1-benzothiazin-2-yl)sulfanyl] alkanes using 1,omega-alkanedithiols.
