摘要
A series of substituted 1,8-naphthyridine-3-carboxylates were synthesized for the first time from the Baylis-Hillman adducts obtained from 2-chloronicotinaldehyde derivatives. Three methods were adopted to synthesize 1,8-naphthyridine-3-carboxylates, of which the azide-reduction route (Scheme 5) gave the best yields compared to the other attempted methods (Schemes 2 and 3).
