Convenient Synthesis of [1,5-c]Quinazolo-2,3-dihydro-1,2,4,3-triazaphospholes and [1,5-C]Quinazolo-2,3-Dihydro-1,2,4,3-triazaphosphole-3-sulfides

The condensation of the amino-iminoquinazolines 2, with tris(dimethylamino) phosphine, leads to corresponding [1,5-c]quinazolo-2,3-dihydro-1,2,4,3-triazaphospholes 3. Oxidation of compounds 3 with sulfur gives the quinazolo-triazaphosphole-sulfides 4. The structure of these compounds is unambiguously confirmed by IR, 1 H, 31 P, and 13 C NMR spectroscopy and by microanalysis of some of the products.
