Abstract
A short and facile synthesis of a series of 3-aryl-3,4-dihydroquinazolin-2(1H)-ones was accomplished in good yields via the novel reductive cyclisation of 2-nitrobenzylamines with bis(trichloromethyl)carbonate (triphosgene) promoted by TiCl4/Sm system. The structures of the products were characterised by IR, 1H NMR and elemental analysis and the structure of 3a was confirmed by X-ray diffraction analysis.
