K. Mogilaiah*, R. Shiva Prasad and K. Jagadeeshwar
Abstract:
2-Aminonicotinaldehyde 1 with various carbonyl compounds containing รก-methylene group 2 undergo Friedlander condensation on the surface of SiO2 when subjected to microwave irradiation generating 1,8-naphthyridines 3 in high yields.
Keywords:2-Aminonicotinaldehyde; carbonyl compounds containing a-methylene group; Friedlander condensation; 1,8-naphthyridines, SiO2; microwave irradiation
