Sulfamic acid: An efficient, cost-effective, and reusable solid acid catalyst for the synthesis of 1,8-naphthyridines under solvent-free heating and microwave irradiation

Reddy, Y. Thirupathi,Reddy, P. Raghotham,Reddy, M. Nikhil,Rajitha,Crooks, Peter A.

, p. 3201 - 3207 (2008/12/22)

An efficient and convenient method is described for the synthesis of 1,8-naphthyridines in excellent yields by condensation of 2-aminonicotinaldehyde with various active methylene compounds in the presence of sulfamic acid as the catalyst in a solvent-free media using both conventional heating and microwave irradiation.
