Synthesis of New Coumarin Scaffold Bearing 2-Iminochromene Moiety

Coumarin is classified as one of interesting therapeutic starting research points to obtain remarkable compounds with high efficacy. So, during this research, new 2-iminochromene derivatives bearing coumarin moiety were synthesized. At first, cyanoacetohydrazone 3-acetylcoumarin was prepared and used the material. The synthesized through ring closure derivative 4-hydroxysalicylaldehyde, 5-aryldiazosalicylaldehydes, 2-hydroxynaphthaldehyde 7-hydroxychromone-6-carboxaldehyde derivative. All newly obtained in excellent yields; so, will participate enrichment chemical libraries.
