Reactions of 2-acyl-1,3-dimethylindole oximes and of 2-acylamino-1,3-dimethylindole with arenesulphonyl azides

Abstract

2-Acyl-1,3-dimethylindole oximes react with arenesulphonyl azides to form derivatives of dihydroisoxazolo[4,5-b]-indole. The hydrolysis and methylation of these compounds have been examined. Beckmann rearrangement of the oximes yielded 2-acylamino-1,3-dimethylindoles and these compounds reacted with arenesulphonyl azides affording 2-acylimino-3-arylsulphonylamino-1,3-dimethylindolines.
