Abstract

Upon irradiation in the presence of diethyl acetylenedicarboxylate 6,7-dimethoxy-2-phenyl-4H-1,3-benzothiazine gives two main products: benzonitrile (X) and 2,3-carbethoxy-4,5-dimethoxy-7-methylbenzothiophene (XI). We report herein the first photochemical reaction of a 4H-1,3-benzothiazine derivative.
