摘要：

A modified Friedlander condensation of 2-aminonicotinaldehyde with alpha- and beta-naphthols lead successfully to two new naphtho[1,2-b and 2,1-b][1,8]-naphthyridines in a single synthetic procedure. The oxidation of the naphthonaphthyridines with peroxy acids afforded novel products such as a seven-membered oxazepine moiety. Structures were characterized by standard spectroscopy. The crystal and molecular structures (3) and (4) were determined by X-ray analyses.
