N-Phenylsulfonimidoyl chloride reacts with trimethylsilylethene in the presence of aluminum chloride to give two product benzothiazines, one of which has been desilylated. The silylated benzothiazine can be deprotonated and alkylated, sometimes with very high diastereocontrol. Upon treatment with fluoride, these silylated benzothiazines undergo desilylation with concomitant cleavage of the carbon-sulfur

Reduction of selected 2,1-benzothiazines with sodium amalgam leads to the formation of 2-alkylanilines in high yield. Since the benzothiazines are ultimately derived from aniline, the process constitutes a general, regioselective functionalization of aniline not readily achieved by other means.
