One-Pot Three-Component Synthesis of Imidazo[1,5-a]pyridines
A one-pot three component condensation synthesis of imidazo[1,5-a]pyridines using of various aromatic aldehydes and dipyridil ketone with ammonium acetate in the presence of Lithium chloride as catalyst in good yields under microwave irradiation has been described.
متن کاملOne-pot synthesis of tetracyclic fused imidazo[1,2-a]pyridines via a three-component reaction
A novel three-component reaction has been developed to assemble biologically and pharmaceutically important tetracyclic fused imidazo[1,2-a]pyridines in a one-pot fashion utilizing readily available 2-aminopyridines, isatins and isocyanides. The three-component coupling proceeds through the Groebke-Blackburn-Bienaymé reaction followed by a retro-aza-ene reaction and subsequent nucleophilic reac...
متن کامل(1H-Imidazol-4-yl)methanol
The title compound, C4H6N2O, displays two predominant hydrogen-bonding inter-actions in the crystal structure. The first is between the unprotonated imidazole N atom of one mol-ecule and the hy-droxy H atom of an adjacent mol-ecule. The second is between the hy-droxy O atom of one mol-ecule and the imidazole N-H group of a corresponding mol-ecule. These inter-actions lead to the formation of a ...
متن کاملSynthesis of benzofuro[2,3-c]pyridines via a one-pot three-component reaction.
A convenient one-pot reaction was conducted by mixing bromoacetophenone, a functionalized α,β-unsaturated ketone and potassium hydroxide in tetrahydrofuran at room temperature, ammonium acetate was added and heated to reflux, resulting in four chemical bonds forming from easily accessible substrates. This process provides a flexible and rapid synthetic route for the construction of polysubstitu...
متن کاملOne-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.
