  Abstract A green procedure for the rapid diversification of quinazolin-4-(1H)-one scaffolds is described in this paper. Various types of 1,2-dicarbonyl compounds are treated with 2-aminobenzamides in ionic liquids catalyzed by iodine and unexpectedly afford structurally diversified single-quinazoline derivatives. The recyclability of the ionic liquids makes this protocol to be an environmentally benign

  A highly efficient and environmental benign procedure for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones via the condensation of carbonyl compounds with 2-aminobenzamide using a glycerol based ionic liquid with a boron core as a new and reusable promoting medium is described. A broad range of substrates including aldehydes and ketone were condensed with 2-aminobenzamide. All reactions are completed in short times and the products are obtained in good to excellent yields. The reaction medium could be recycled and reused several times without any loss of efficiency. Moreover, presented procedure has been applied successfully for the synthesis of some novel bis(pyrazolinone) derivatives. (C) 2013 Elsevier B.V. All rights reserved.
