A green and efficient method for regioselective O-acylation of polyphenols has been developed. The acylation can be carried out in potassium carbonate/dimethyl sulphoxide system by utilizing the ‘inherent nucleophile’ via an intermolecular cooperative transesterification under mild condition. This method shows particular advantage in regioselective acylation of polyphenols bearing 2′,4′-dihydroxyacetophenone moiety and can be extended to the synthesis of mono or multiple acetates of polyphenols without this moiety in good yields. Compared with other reported approaches, this method is endowed with atom economy and is more environment-friendly for avoiding the use of any metal-based catalysts.

Flash vacuum pyrolysis studies of substituted 6-acetoxy-2,4- cyclohexadienones (3 and 10) from 300 to 500 C provide strong experimental evidence that direct [3,5]-sigmatropic rearrangements in these molecules are favored over the more familiar [3,3]-sigma
