Polyvinylpolypyrrolidone supported chlorosulfonic acid: An efficient catalyst for the one-pot synthesis of hexahydroquinolines
ABSTRACT Polyvinylpolypyrrolidone supported chlorosulfonic acid ([PVPP-SO3H]+Cl-) was synthesized and evaluated as a recoverable catalyst for the one-pot synthesis of hexahydroquinolines by reaction of arylaldehydes, dimedone (5,5-dimethylcyclohexane-1,3-dione) or 1,3-cyclohexanedione, ethylacetoacetate and ammonium acetate in high to excellent yield in ethanol at 70 °C. The [PVPP-SO3H]+Cl- cat...
متن کاملAn 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 2-aminothiazole derivatives
A highly efficient, rapid and catalyst free protocol has been developed for the synthesis of 2-aminothiazoles in tetrahydrofuran (THF). Reaction was carried out at room temperature and the products were obtained in high yields without further purification.
متن کاملSbCl3 as an Efficient Catalyst for the One-pot Synthesis of Highly Substituted Piperidines
Highly substituted piperidines were synthesized via the condensation of aromatic aldehydes and aromatic amines with β-ketoesters in the presence of antimony(III) chloride at ambient condition. This reaction has any advantages such as easy work-up, clean procedure, and good yields.
