A series of novel aryl-substituted β-lactams condensed with 1,3-benzothiazines, isoquinolines or 1,4-benzothiazepine were obtained by means of the Staudinger reaction and isomerized in the presence of sodium methoxide to the thermodynamically more stable
CYCLOADDITION REACTIONS OF 1,3-BENZOTHIAZINES-I. REACTIONS OF 2-PHENYL-4H- AND 4-PHENYL-2H-1,3-BENZOTHIAZINE DERIVATIVES WITH SUBSTITUTED ACETYL CHLORIDES

6,7-Dimethoxy-2-phenyl-4H-1,3-benzothiazine (1) and 6,7-dimethoxy-4-phenyl-2H-1,3-benzothiazine (2) react with substituted acetyl chlorides to give linearly, and new angularly condensed β-lactam derivatives (4,5).Heating of the latter compounds with hydro
