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 کاملAn efficient one-pot synthesis of dimethyl 1-(Aryl)-5-cyano-4-(cyclohexylamino)-1,2,5,6-tetrahydro-6-oxopyridine-2,3-dicarboxylate derivatives
Abstract: The reactive 1:1 intermediate produced in the reaction between cyclohexyl isocyanide and electron- deficient acetylenic esters or dimethyl acetylene dicarboxylate was trapped by 2-cyano-N-(Aryl) acetamides to provides highly functionalized oxopyridine (potential synthetic and pharmaceutical interest ) in acetonitrile under mild reaction conditions at ambient temperature after 24 h ...
متن کاملA One-Pot Tandem Olefin Isomerization/Metathesis-Coupling (ISOMET) Reaction
A tandem catalytic reaction has been developed as part of a process to discover tungsten-based olefin metathesis catalysts that have a strong preference for terminal olefins over cis or trans internal isomers in olefin metathesis. This tandem isomerization/terminal olefin metathesis reaction (ISOMET) converts Cn trans internal olefins into C2n−2 cis olefins and ethylene. This reaction is made p...
متن کاملNanocrystalline TiO2 as an efficient and reusable catalyst for the one-pot synthesis of polyhydroquinolien derivatives via Hantzsch reaction
An efficient synthesis of polyhydroquinoline derivatives was reported via four-component coupling reactions of aldehydes, 1,3-dicarbonyl ketones (dimedone or 1,3-cyclohexanedione), ethyl acetoacetate or methyl acetoacetate and ammonium acetate in the presence of a catalytic amount of nanocrystalline TiO2 under solvent free conditions. The reported method is mild, rapid and has the advantages su...
متن کاملLaCl3.7H20: An efficient catalyst for one-pot multi-component synthesis of 1,4-polyhydroquinoline derivatives through unsymmetrical Hantzsch reaction
An efficient one pot multi component synthesis of 1, 4-Polyhydroquinoline derivatives through unsymmetrical Hantzsch reaction using lanthanum chloride heptahydrate (LaCl3.7H2O) from an aromatic aldehyde, ethyl acetoacetate, dimedone and ammonium acetate as a nitrogen precursor in ethanol at room temperature is described. In the present work we report lanthanum chloride heptahydrate remarkably n...
