Abstract
Reaction of readily available α-(benzotriazolyl)alkyl urea derivatives (derived from aromatic, heteroaromatic, and aliphatic aldehydes) with β-keto esters resulted in 3,4-dihydropyrimidin-2(1H)-ones in good to excellent yields.
Key words
urea - heterocycles - pyrimidines - condensation - esters - cyclizations
