The N-(3-quinazolinio)amidates 1a-1f react with acetone in the presence of butylamine to furnish two isomeric 1:1 adducts (type 3 and 4); in one case (1f) a 2:1 condensation product (5) was formed.In the presence of silica the amidates 1a and 1b furnish with acetone only type 3 adducts.The type 3 adducts are analogous to those formed by the addition of O- and N-nucleophiles across the C(4)-N(3)-N bonds of N-(3-quinazolinio)amidates.IR, 1H NMR and mass spectra of the adducts are described, as well as the X-ray molecular structure determination of compounds 4f and 5.
