Abstract
Abstract Bronsted acidic ionic liquid, 1-methylimidazolium hydrogen sulfate, in the presence of catalytic amount of chlorotrimethylsilane has been used as an efficient and reusable catalyst for the one-pot synthesis of 3,4-dihydropyrimidin-2(1 H )-ones and hydroquinazoline-2,5-diones under thermal and solvent-free conditions. High yields of the products were obtained in a few minutes by using this new catalysis system.
