Oxazoles formation during O-alkylation of isonitroso-naphthols. X-ray structure of [1,2]naphthoquinone 1-[O-(4-tert-Butyl-benzyl)oxime] and 2-(4-tert-Butyl-phenyl)napth[1,2-d]oxazole

1-Nitroso-2-naphthol and 2-nitroso-1-naphthol, both in the isonitroso form, react with benzyl bromides in THF and in the presence of triethylamine affording, in low yields, the corresponding O-benzyl oximes and 2-aryl naphthoxazoles in a 1:1 ratio, approximately. The structures of O-benzyl oximes and naphthoxazoles isolated have been determined by X-ray analysis.

Reactions between 1-nitroso-2-naphthols and α-functionalized ketones such as α-bromo-, α-chloro-, α-mesyloxy-, α-tosyloxy-, and α-hydroxy ketones under basic conditions delivered 2-substituted naphtho[1,2-d][1,3]oxazoles in a single synthetic operation. T

A 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 described. This method consists of the decomposition of naphtho-and benzoxazinones with KOH.
