Abstract
A single-step, facile synthesis of 1,8-naphthyridine derivatives in good yields was carried out at room temperature under mild conditions using a three-component condensation reaction of substituted 2-aminopyridines, malononitrile or methyl/ethyl cyanoacetate, and various aldehydes in the presence of a N-bromosulfonamide as Lewis acid.
