One-Pot Three-Component Synthesis of Newβ-Indole Derivatives in Gluconic Acid Aqueous Solution

One-pot Three-component Synthesis of Phosphonate Derivatives

The stable phosphonate derivatives have easily synthesized by the reactions involving trialkyl(aryl) phosphites and dimethyl acetylenedicarboxylate in the presence of 4-nitrophenol and/or acid chlorides, dialkyl(aryl) phosphites and N-methylimidazole at 70 oC under solventfree conditions.

Four-Component, One-Pot Synthesis of Novel Conjugated Indole-Imidazole Derivatives

A series of new tetrasubstituted imidazoles 2-phenyl-3-(1, 4, 5-triphenyl-1H-imidazol-2-yl)-1H-indole derivatives substituted with –F, Cl, Br, I,-OCH3 and -NHCOCH3 were synthesized using a multicomponent reaction. The compounds were obtained in good yields by easy workup and with high purity

An Efficient Synthesis of 4H-chromene Derivatives by a One-pot, Three-component Reaction

A facile and efficient one-pot, multicomponent synthesis of 4H-chromenes is reported, through the reaction of arylglyoxalmonohydrates with 1,3-diketones and malononitrile in eTEMPthanol in the presence of L-proline as a catalyst.

One pot three-component synthesis of imidazole derivatives using NH3/NH4Cl

Imidazole is a planar, five membered heteroaromatic molecule with pyrrole type and pyridine type annular nitrogens. Several approaches are available of imidazoles from alpha halo ketones, aminonitrile, aldehyde ect. Reactivity of imidazole and benzimidazole is referred from sets of  resonance structure in which the dipolar contributors have finite importance. Imidazoles among the principal grou...
