Abstract

A new synthetic method to obtain functionally substituted 1,4,2-dioxazoles from vinyl aryl ethers and hydroxamic acids was proposed. The target heterocycles were formed under mild conditions in good yields. It was shown that ring closure occurs via the formation of aroxy(methyl) arylhydroxamates as intermediates.
