✦ Synopsis

An efficient heterogeneous catalytic method for the synthesis of a-hydroxy ketones from a-diazo carbonyl compounds 1, 3 and 6 in the presence of Amberlyst-15, a macro reticular ion exchange resin, is reported. The desired products were obtained at room temperature or by ultrasonication in good yield. Interestingly, novel fused 3-furanones and bicycloalkane-1,3-diones were obtained as unusual products in the case of alicyclic a-diazo carbonyl compounds.

The rational synthesis of diazocyclopentadiene by the reaction of cyclopentadienyllithium with tosyl aside designed by Doering and De Puy(1) more than a decade ago has only recently been extended to the preparation of other diazo compounds (2,3,4,5). Regitz(&,j) has reported its application
