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.
