Abstract

The photo Fries rearrangements of esters of 1-naphthol and 5-methoxy-1-naphthol to the corresponding 1-hydroxy-2-acylnaphthalenes have been carried out. The best yield (70%) was obtained by irradiating 5-methoxy-1-naphthyl acetate in ethyl acetate. By contrast the yield from 1-naphthyl acetate under simi conditiona was 40%. Oxidation of l-hydroxy-5- methoxy-2-naphthyl cyclohexyl ketone with thallium trinitrate gave the corresponding 1, ...
