Naphthyridines, synthesis and pharmacology of 85KFZ790. Naphthyridines, synthesis and reactivity 79KGS3. 

McWilliams and coworkers (03JOC467) have studied the catalytic activity and selectivity of bases as catalysts in the [l,8]naphthyridine synthesis from 2-aminonicotinaldehyde 357 (69BSB289, 74JOC720, 80T2359, OlMIl, 01SC1573) and 2-pentanone. As shown in Table 4, many different Bronsted and Lewis bases promote this reaction. The best in terms of acceleration and regioselectivity is pyrrolidine (03JOC467).
