Article abstract of DOI:10.1016/j.tet.2014.03.075

The domino reaction of (E)-2-amino-N′-(1-arylethylidene) benzohydrazide and triethyl orthoformate in ionic liquids catalyzed by 10 mol % iodine gave 3a,4-dihydro-2-arylpyrazolo[5,1-b]quinazolin-9(3H)-one derivatives unexpectedly. In the presence of K
