Several 1-aryl[1]benzoxepinopyrazoles were prepared by reaction of 4- hydroxymethylene[1]benzoxepinones with appropriate phenylhydrazine hydrochlorides. The direct condensation of hydroxymethylenebenzoxepinones with variously substituted amidines failed to give benzoxepinopyrimidines. These compounds were obtained via the key intermediates morpholine enaminobenzoxepinones.

Abstract
Several 1-aryl[1]benzoxepinopyrazoles were prepared by reaction of 4- hydroxymethylene[1]benzoxepinones with appropriate phenylhydrazine hydrochlorides. The direct condensation of hydroxymethylenebenzoxepinones with variously substituted amidines failed to give benzoxepinopyrimidines. These compounds were obtained via the key intermediates morpholine enaminobenzoxepinones.File in questo prodotto:
