A Facile and Green Approach for One-Pot Synthesis of New Pyrrole Derivatives by Three-Component Reaction Between Pyrrole, Arylglyoxals and Meldrum's Acid

An efficient one-pot three-component reaction of pyrrole with arylglyoxal derivatives and Meldrum’s acid (MA) in water at room temperature afforded ۲,۲-dimethyl-۵- (۲-oxo-۲-aryl-۱- (۱H-pyrrol-۲-yl) ethyl) -۱,۳-dioxane-۴,۶-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.
