STUDIES IN THE ƴ-KETONIC ACIDS. PART II.

Methyl succinic anhydride has been condensed with phenol, anisole, resorcinol dimethyl ether and pyrogallol trimethyl ether giving rise to \(\beta\)-aroylpropionic acids, which have been reduced to the corresponding \(\gamma\)-arylbutyric acids. The latter have been cyclised to ketotetrahydronaphthaleaes from which the corresponding naphthalenes have been obtained by dehydrogenation.
