Abstract

Cyclization of the 2-phenoxathiin 10,10-dioxide hydrazone of ethyl pyruvate in ethyl polyphosphate results in the concurrent formation of the respective cyclic esters of both angular and linear structures. The parent compounds of a new condensed heterocyclic system of pyrrolophenoxathiin dioxides are synthesized from the latter.
