There are a few examples of 1,2-thiazine synthesis of this type which are of importance. The most noteworthy is the preparation of 4-hydroxy-2/f-l,2-benzothiazine 1,1-dioxides (199) from the benzisothiazolinone (200) <81AHC(28)73>. This general procedure can be extended to the preparation of 2-alkyl-4-hydroxybenzothiazines. The treatment of A-methylsaccharin (201) and an alkyl chloro-acetate with NaH in DMSO or DMF affords a 76% yield of the 1,2-benzothiazine (202) (Scheme 39) <83JOC3601, 86CCC 1113,86FES819>. [Pg.379]
