Substituted (4Z)-4-benzylidene-2-methyl-4H-1,3-benzothiazines (1) and (4Z)-2-ethyl-4-benzylidene-4H-1,3-benzothiazines (2) were synthesized by direct stereoselective reactions of S-phenyl ethanethioate or S-phenyl propane-thioate with substituted benzyl nitriles in the presence of triflic anhydride.
