Artículo de publicación ISIA method that allows the synthesis of 4 different heterocyclic systems of fused aryl oxazoles, i.e., naphtho[1,2-d], naphtho[2,1-d], naphtho[2,3-d], and benzo[d]oxazoles in reasonable yield is del scribed. This method consists of the decomposition of naphtho- and benzoxazinones with KOH
