REACTION OF PERI-ACYLOXYNAPHTHYL BROMOMETHYL KETONES WITH O- AND N-CONTAINING NUCLEOPHILES
Peri-acyloxynaphthyl bromomethyl ketones are converted into naphthopyran-3-ones by the action of aliphatic amines and into naphthofuran-2-one when heated in pyridine.In reaction with aromatic amines or sodium acetate they substitute the bromine by
