3-乙酰基香豆素 | 3-acetylcoumarin | 3949-36-8 | C11H8O3 | 188.183 |
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 of 3-acetylcoumarin was prepared and used as the starting material. The 2-iminochromene derivatives were synthesized through the ring closure of cyanoacetohydrazone derivative with 4-hydroxysalicylaldehyde, 5-aryldiazosalicylaldehydes, 2-hydroxynaphthaldehyde and 7-hydroxychromone-6-carboxaldehyde derivative. All of the newly synthesized coumarin derivatives were obtained in excellent yields; so, the new synthesized coumarin derivatives will participate in the enrichment of the chemical libraries.
