A total of 25 benzo[
j][1,7]phe
nanthroline and cyclopenta[
j][1,7]phe
nanthroline derivatives were synthesized in EtOH under catalyst-free conditions. This procedure included a three-component reaction of aromatic aldehydes,
pan class="TH_term3">quinolin-7-aminepan>, and active methylene compounds and provided an efficient and green access to the synthesis of [1,7]phe
nanthrolines in high yields.
