摘要：
An efficient chemoselective synthesis of 4-aryl-2,3-dihydropyrimido[1,2-a]benzimidazol-2-one derivatives from three-component reactions of 2-aminobenzimidazole, Meldrum's acid, and aldehydes via [3+3] atom combination is described. The reaction occurs in different conditions such as in DMF as solvent at reflux and in the presence of l-proline as base catalyst.
