7-Hydroxy-4-(4-methoxyphenyl)-3,4-dihydrocoumarin

The heterocyclic ring of the title compound, C16H14O4, is in a half-chair conformation. The best planes through the two phenyl rings make an angle of 61.0(1) °. The packing of the molecules is stabilized by intermolecular

Synthesis and Hydroxyl Radical Scavenging Activity of 4-Aryl-3,4-Dihydrocoumarins

Twelve 4-aryl-3,4-dihydrocoumarins were synthesized by the condensation of phenols with the corresponding substituted cinnamic acids in the presence of nitrobenzene and sulfated montmorillonite K-10. This method displayed the property of green chemistry w

Preparation method of 3,4-dihydro-4-arylcoumarin compounds

The invention relates to the field of chemical synthesis, and concretely relates to a preparation method of 3,4-dihydro-4-arylcoumarin compounds. The method is characterized in that: substituted benzaldehyde is used as an initial raw material, propane diacid is added, a reaction is carried out with catalysis of piperidine, and substituted phenyl acrylic acid derivatives are obtained; montmorillonite K-10 which is acidified by sulfuric acid is used as a catalyst, a reaction between the substituted phenyl acrylic acid derivatives and phenolic compounds is carried out with heating, and the 3,4-dihydro-4-arylcoumarin compounds are obtained. Compared with the prior art, the preparation method of the 3,4-dihydro-4-arylcoumarin compounds has the advantages of easily available and cheap raw materials, simple operation, recyclable catalyst, environmental protection, simple post-treatment, low production cost, good promotion application, etc.
