Abstract

New derivatives of coumarin, containing annulated  α-pyrone rings, were obtained by reaction of the borate complexes of three isomeric acyl(hydroxy)coumarins with acid anhydrides. It was shown that the borate complex of 3-acetyl-4-hydroxy-2-pyrone  also condenses with acetic anhydride to form a derivative containing a new annulated α-pyrone ring.
