Claimed 2,1-benzisoxazoles are indazalones.

Mark J Kurth1, Marilyn M Olmstead, Makhluf J Haddadin.   

Abstract

Claims, by two groups, to have prepared 2,1-benzisoxazole derivatives are corrected to show that the products are indazalones (5). In addition, a simple preparation of 3-oxy-substituted 2H-indazole, by an unrecognized method in the literature, is reported.
