Abstract

4-Aminopyridine-3-carboxylic acid (4-aminonicotinic acid) and its ester are sometimes found as a partial structure in natural products, 1 and their derivatives behave as NAD analogs. 2 4-Aminopyridines (4APs) having a functional group at the vicinal position are also excellent precursors for [c]-fused pyrido compounds such as pyridopyrimidine, imidazopyridine, pyrazolopyridine and naphthyridine, those are widely used for medicines or their synthetic intermediates. 3 ...
