Abstract

A method that allows the synthesis of 4 different heterocyclic systems of fused aryl oxazoles, ie, naphtho [1, 2-d], naphtho [2, 1-d], naphtho [2, 3-d], and benzo [d] oxazoles in reasonable yield is described. This method consists of the decomposition of naphtho-and benzoxazinones with KOH.
