Abstract

β-(N-Triphenylphosphoranyliden)-enamino esters afford the synthetically useful heteroannulated 3, 1-oxazin-4-ones with aroyl chlorides in different solvents. The reaction proceeds in one step and in high yields and appears to be independent of the reactivity of the heterocyclic substrate.
