An efficient one-pot three-component reaction of pyrrole with arylglyoxal derivatives and Meldrum’s acid (MA) in water at room temperature afforded 2,2-dimethyl-5- (2-oxo-2-aryl-1- (1H-pyrrol-2-yl) ethyl) -1,3-dioxane-4,6-dione derivatives under catalyst-free conditions in high yields. Products were isolated and purified by simple filtration and washing with diethyl ether and their structures were established from their IR and NMR spectroscopic data.
