Ultrasound Assisted One-pot Synthesis of Dihydropyrimidinones Using Holmium Chloride As Catalyst
A simple and green chemical procedure was reported for the synthesis of dihydropyrimidinones from various aldehydes, ethyl acetoacetate and urea or thiourea using holmium chloride as catalyst. The reactions were performed under solvent free conditions with ultrasound irradiation as the energy source. The advantages of this protocol include the excellent yield, operational simplicity, short tim...
متن کاملCholine chloride: 2 ZnCl2 catalyzed efficient one-pot regioselective synthesis of dihydrobenzofuro[2,3-b]benzofuran
The reaction of 2-naphthol and also para-substituted phenols with glyoxal in presence of choline chloride: 2 ZnCl2 [ChCl: 2ZnCl2], a deep eutectic solvent (DES), as a green catalyst was studied. The amount of catalyst, solvent type, temperature, and time on the yield of reaction were investigated. It was found that the optimal condition included 10% mol ratio of catalyst (mol percentage of DES ...
متن کاملCobalt(II) chloride catalyzed one-pot synthesis of α-aminonitriles
A simple and efficient method has been developed for the synthesis of alpha-aminonitriles by a one-pot three- component condensation of aldehydes, amines, and potassium cyanide in acetonitrile in the presence of a catalytic amount of CoCl2 at room temperature.

متن کاملHighly efficient one-pot four-component synthesis of polyhydroquinoline derivatives catalyzed by stannous chloride under solvent-free conditions
A rapid and efficient one-pot, four-component protocol towards the synthesis of polyhydroquinoline derivatives has been developed. The condensation of aldehyde, dimedone, ethyl acetoacetate and ammonium acetate in presence of stannous chloride was carried out under solvent free condition to synthesize a variety of polyhydroquinoline derivatives in good to excellent yields. Stannous chloride was...
