Synthesis of Imidazonaphthyridines and -quinolines
摘要:
Four 2-amino-3-methylimidazo[4,5-b][1,x]naphthyridines, x = 5-8 (6-9) have been obtained from aromatic aldehydes (11-14) and 2-amino-1-methyl-2-imidazolin-5-one (15) in one step. The N-1 - and N-3 -methyl isomers of 2-aminoimidazo-[4,5-b]quinoline (5 and 10) were prepared from 2-nitrobenzaldehyde via the isolated E-isomers of imidazolin-5-one (17) and imidazolin-4-one (20).
