One-Pot Multi-Component Synthesis of Dihydropyrimidinones via Biginelli Condensation
Three-component reactions have emerged as useful methods because the combinationof three components to generate new products in a single step is extremely economical,among the multi-component reactions. A green, simple, efficient, and cost-effective procedure has been carried out by the synthesis of dihydropyrimidinonesin Biginelli’s condensation of ethyl cyanoacetate, aldehyde and urea or thio...
متن کاملUltrasound based method for one-pot synthesis of substituted imidazoles using SiO2-OSbCl2 as highly effective and reusable catalyst
A simple highly versatile and efficient sonochemical synthesis of 1,2,4,5-tetrasubstituted and 2,4,5-trisubstituted imidazoles is achieved by condensation of 1,2-dicarbonyl compound, aldehyde, ammonium acetate and primary amine using antimony trichloride immobilized on silica gel (SiO2-OSbCl2) as a catalyst in ethanol at moderate temperature. Operational simplicity, practicability and applicabi...
متن کاملCaro’sacid-silicagel: An Efficient and Reusable Catalyst for the Synthesis of 2, 4, 5- Trisubstituted Imidazoles under Solvent-free Conditions
Caro’s acid-silicagel was found to be a mild and effective catalyst for the one –pot multicomponent condensation of benzyl, aldehydes and ammonium acetate used for synthesis of 2, 4, 5-trisubstituted imidazole derivatives under solvent–free conditions. This catalyst has several advantages such as simple work-up, low cost and reusability.
