An unprecedented methodology for the synthesis of a variety of organic amides through the coupling of wide range of unactivated primary, secondary, and tertiary diversified amides, with different amines is reported. The acid-promoted reaction is proposed to proceed through carbonyl activation and is accompanied by broad substrate scope with high tolerance for functional groups.
and simple three‐component domino synthesis of some new dihydropyrimidines (DHPMs) from aromatic aldehydes, 1,3‐dicarbonyl compounds and N‐(3‐chloro‐4‐fluorophenyl)urea using molecular iodine as catalyst is described. The 1‐substituted dihydropyrimidines were isolated in good to excellent yields (78‐90%) within a short reaction time (4‐6 h) at ambienttemperature. The biological evaluation revealed

DNA synthesis by human cytomegalovirus (HCMV)-infected human embryonic lung (HEL) cells in culture. In general, active compounds had moderate to low selectivity for viral vs host cell DNA synthesis. Nucleoside and acyclonucleoside analogs of 2-(3,5-dichloroanilino)purines inhibited both HCMV and cellular DNA synthesis at similar concentrations. 2-Amino-4-chloro-6-(3,5-dichloroanilino)pyrimidine and
