Some new 3-[3-(1-phenyl-3-aryl-1H-pyrazol-4-yl) acryloyl] coumarins 3a-f were synthesized (coumarin chalcones) by the condensation of various 3-acetyl coumarins 1 and appropriate 1-phenyl-3-aryl-1H-pyrazole-4-carbaldehyde 2. These coumarin chalcones 3a-f were then employed for the synthesis of pyrazolyl bipyridinyl substituted coumarins 7a-f, 8a-f, and 9a-f under Krohnke’s reaction condition.

Abstract:
In the present work, we report a convenient synthesis of 5- and 7-substituted-4-phenyl coumarins. In contrast to previous results obtained with 4-alkylcoumarins, nicotinoylation of 5,7-dihydroxy-4-phenylcoumarin with nicotinoyl benzotriazole or nicotinoyl azide selectively provides 5-O protected ester. The combination of the nicotinoylation reaction followed by tosylation-denicotinoylation yields 5-hydroxy-7-tosyloxy-coumarin derivative, which may be useful in the synthesis of inophyllum, a tetracyclic HIV reverse transcriptase inhibitor, as well as its analogues.

Plant metabolites having one or more hydroxyl groups attached to an aromatic ring are known as phenols. Phenols are a heterogeneous group of compounds. One of the most important functions of phenols is in plant communication e.g., allelopathy, attracting pollinating and disseminating agents, attracting symbiotic bacteria, and inhibiting pathogens and predators. Some phenolic compounds (e.g., lignin) are structural components of plant cell wall. Phenols also protect the plant from oxidants and ultraviolet radiation.
