1,4-Benzothiazines and related compounds

Brown, C., Davidson, R. M., 1,4-Benzothiazines, Dihydro-1,4-benzothiazines, and Related Compounds, 38, 135. [Pg.330]

Angelini described the preparation of dihydro- 1,4-benzothiazine and related compounds from analogous esters by a two-stage reduction using tin and HC1 or lithium aluminum hydride.129 It is interesting to compare the reaction of 2-nitrophenol with similar reagents to produce benzooxazine derivatives. 2-Nitrophenol reacts with a-bromoethyl acetate, and the adduct is cyclized with zinc and ammonium chloride to the hydroxamic derivative 85.130 The adduct with phenacyl chloride has been similarly cyclized under a variety of conditions.131,132... [Pg.160]
