Functionalization of benzo[b][1,6]naphthyridine derivatives
Ivanov,Tugusheva,Alekseeva,Granik
, p. 1182 - 1189 (2003)
Two routes to consecutive functionalization of 3-chloro-4-cyanobenzo[b][1, 6]naphthyridine (1a) at positions 3 and 10 were developed. Oxidation of compound 1a with m-chloro-perbenzoic acid in acetone leads to 3-chloro-4-cyano-10-oxobenzo[b][1,6]naphthyrid
