One-pot synthesis of dibenzo[b,h][1,6]naphthyridines from 2-acetylaminobenzaldehyde: application to a fluorescent DNA-binding compound
Dibenzo[b,h][1,6]naphthyridines were synthesized in one pot by reacting 2-acetylamainobnezaldehyde with methyl ketones under basic conditions, methylation of which showed strong fluorescence.
