Synthesis of (Z)-2-(4-(arylimino)-3, 4-dihydroquinazolin-2(1H)-ylidene)-1H-indene-1, 3(2H)dione using 2-amino-N'-aryl-benzimidamides as a starting material

摘要

The reaction between 2-amino-N'-arylbenzimidamide derivatives (3a-g) and 2-dicyanomethyleneindan-1,3-dione (4, CNIND) is described. The product that was obtained in moderate to good yields via CT-complexation is identified as (Z)-2-[4-(arylimino)-3,4-dihydroquinazolin-2(1H)-ylidene]-1H-indene-1,3(2H)-dione (5a-g).
