One-pot synthesis of Benzimidazole derivatives under microwave Irradiation and solvent-free condition

A simple, fast, efficient and environmentally friendly method for synthesis of benzimidazole and its 2-alkyl, aryl and heteroaryl substituted derivatives was developed using zeolite HY. Two component cyclolcondensation of 1,2-phenylenediamine (o-phenylenediamine) and commercially available carboxylic acids catalyzed by zeolite HY without any solvent, under microwave irradiation led to formation...

CuCl2 Catalyzed Solvent-free One Pot Synthesis of Dihydropyrimidinones

An Efficient Synthesis of 3,4-Dihydropyrimidin-2-(1H)-one Derivatives Promoted by Antimony Trichloride under Thermal and Solvent-free Conditions

An efficient and simple one-pot approach for the synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives using antimony trichloride (SbCl3) as a mild catalyst by means of three-component Biginelli reaction between β-keto esters, aldehyde derivatives and urea/thiourea under thermal and solvent-free conditions with excellent yields and short reaction times is reported. This m...
