confirmed the scheme suggested by Baker,3 and revealed that the reaction intermediates are enolesters which cyclize to γ-pyrones. Enol benzoate is probably the intermediate also in the Kuhn variant14 of the Allan-Robinson reaction. The Kostanecki-Robinson acylations in non-aqueous media correspond to the cyclization of enol esters2 in aqueous solvents. A kinetic study of the reaction has shown that the rate-determining

potent intercellular cell adhesion molecule‐1 (ICAM‐1) inhibitors, a large number of arylalkylketones, benzophenones, desoxybenzoins and chalcones and their analogs (54 in total) have been synthesized and screened for their ICAM‐1 inhibitory activity. The structure‐activity relationship studies of these compounds identified three potent chalcone derivatives and also demonstrated the possible mechanism
