Rearrangement of 3-Methoxy Substituted Benzisoxazole- and Naphthisoxazolequinones in Dimethyl Sulfoxide Solution

The reactions of the 3-methoxy-isoxazole quinones 1 and 9 in a highly polar solution of dimethyl sulfoxide have been studied.Quinones of type 2,4/11,5/12,6 and 7/13 have been isolated; nmr measurements give a detailed insight into the reaction mechanism.

Quninone Chemistry. Synthesis of 3-Methoxybenzisoxazole- and 3-Methoxynaphthisoxazolequinones

Benzisoxazole-4,7-quinones 4 are prepared by an improved method using oxidative amination of 1 to give 2, followed by amine exchange to 3 and cyclization with lead tetraacetate.Naphthisoxazole-4,9-quinone 7 is obtained from 5 by an analogous procedure.
