Reactions of derivatives of the isoquinoline analog trans-2,2a-diaryl-2,2a- dihydro-5,6- dimethoxy-1H,8H-azeto[2,1-b][1,3]benzothiazin-1-one were studied under basic conditions. Their treatment with sodium methoxide in methanol resulted first in alcoholys
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
