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.
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...

متن کاملTrichloroacetic Acid as an Efficient Catalyst for One-pot Synthesis of Highly Functionalized Piperidines via multi-component Reaction
Trichloroacetic Acid (TCA) was used as an efficient catalyst for the synthesis of highly functionalized piperidines via a one-pot five-component reaction of aromatic amines, aromatic aldehydes and β-keto esters in MeOH at room temperature. The remarkable advantages offered by this method are good yields, simple procedure, short reaction times, no need to column chromatography and an easy wo...
