CHEMISTRY OF 1,8-SUBSTITUTED NAPHTHALENES. XVIII. peri-HYDROXY- AND peri-ACYLOXYNAPHTHYL BENZYL KETONES UNDER THE CONDITIONS FOR THE SYNTHESIS OF ISOFLAVONES

The reaction of 4-methoxy-8-hydroxy-1-naphthyl benzyl ketone with benzoyl and ethoxalyl chlorides of trifluoroacetic anhydride in pyridine leads to the formation of the peri-acyloxy-substituted enol acyloxy derivatives of this ketone, whereas the reaction

CHEMISTRY OF 1,8-SUBSTITUTED NAPHTHALENES. XIII. CONDITIONS FOR THE FORMATION AND HETEROCYCLIZATION OF 1-HYDROXY-8-PHENACYLNAPHTHALENE DERIVATIVES

1-Hydroxy-5-methoxy-8-phenacylnaphthalene was obtained by the acylation of 1-benzoyloxy-5-methoxynaphthalene with phenacyl chloride.When boiled in acetic acid, it closes the five-membered naphthofuran ring.Depending on the conditions and on the type of base, its esters are converted into derivatives of 1-hydroxy-8-naphthoic acid or 2-phenyl-2-acylmethylenenaphthofuran.
