Abstract

The autoxidation of dibenzalacetone oxime in the presence of several kinds of transition metal salts gave 4-hydroxy-5-phenyl-3-styryl-4,5-dihydroisoxazole, accompanied with cinnamonitrile and benzaldehyde. Similar treatment of benzalacetophenone oxime, benzalacetone oxime and their p-substituted derivatives also afforded 4-hydroxy-4,5-dihydroisoxazole derivatives.
