Oxidation of N-carbonylhydrazones of 7-liydroxy-8-acetylcoumarin with lead tetraacetate results in the synthesis of 7,8-diacylcoumarins in good yields. The reaction proceeds via the transformation of a hydroxy into an acyl group reported for the first time in heterocyclic chemistry. (C) 2007 Elsevier Ltd. All rights reserved.
