This paper describes an operationally simple, green and efficient approach for the synthesis of 2-hydroxydeoxybenzoins bearing diverse substituents from the microwave-assisted alkali degradation of 3-aryl-4-hydroxycoumarins in water. The latter compounds were readily prepared from the intramolecularClaisencondensation reaction of methyl 2-(2-arylacetoxy)benzoates in the presence of Cs2CO3-acetone
