5-Aminouracil as a Building Block in Heterocyclic Synthesis: Part III. One-pot Synthesis of Novel Pyrimido[5,4-b]quinoline-2,4,9-triones and Pyrimido[5,4-c]isoquinolines

Autor: Kamal Usef Sadek, Raafat M. Shaker, Mohamed Abd Elrady, Ebtisam Abdel Aziz Hafez

Publikováno v: Zeitschrift für Naturforschung B. 65:1485-1490

An efficient and direct procedure for the synthesis of pyrimido[5,4-b]quinoline-2,4,9-trione and pyrimido[5,4-c]isoquinoline derivatives has been described. The products were characterized by elemental analyses, IR, 1H NMR, 13C NMR and MS spectra.

A novel method for the synthesis of polysubstituted diaminobenzonitrile derivatives using controlled microwave heating

Autor: Kamal Usef Sadek, Raafat M. Shaker, Mohamed Hilmy Elnagdi, Mohamed Abd Elrady

Publikováno v: Tetrahedron Letters. 51:6319-6321

A novel, simple and efficient method for the synthesis of polysubstituted diaminobenzonitriles has been developed that involves reaction of 1,1,3-tricyano-2-aminopropionitrile with nitroolefins under controlled microwave irradiation conditions.
