FUNCTIONALIZATION OF BENZOTHIAZINES VIA A SULFOXIMINE STABILIZED VINYL CARBANION

Benzothiazine 2b is readily deprotonated by n-BuLi to give the first example of a sulfoximine stabilized vinyl carbanion.The latter reacts efficiently with a variety of electrophiles.

LEWIS ACID MEDIATED REACTIONS OF N-PHENYL-(4-METHYLPHENYL)-SULFOXIMIDOYL CHLORIDE WITH ALKYNES. A NOVEL ROUTE TO BENZOTHIAZINES.

A general route to benzothiazines has been developed.Treatment of 1 with a Lewis acid in the presence of an alkyne leads to benzothiazines, often in high yields.
