Synthesis and NMR of 4-Aryl-3,4-dihydrocoumarins and 4-arylcoumarins

This paper described the synthesis and 1H and 13C NMR chemical shifts of a series of 4-aryl-3,4-dihydrocoumarin and 4-arylcoumarin derivatives based on a combination of 1H and 13C NMR, HSQC and HMBC experiments.

Synthesis and antimicrobial activities of 4-aryl-3,4-dihydrocoumarins and 4-arylcoumarins

A new series of 4-aryl-3,4-dihydrocoumarins and 4-arylcoumarins were synthesized by the reaction of substituted cinnamic acids and 3-arylpropiolic acid with the corresponding phenols. These compounds were evaluated for antibacterial activity in vitro. The

Efficient synthesis and biological evaluation of 4-arylcoumarin derivatives

Two bioactive natural 4-arylcoumarins, 5,7,4′-trimethoxy-4- phenylcoumarin (1a), 5,7-dimethoxy-4-phenylcoumarin (1b) and five closely related derivatives 1c-g were synthesized. In vitro evaluation with a catechol subunit for antioxidant and antimicrobial activity, these compounds using standard methods showed that compounds 1d, 1f displayed promise radical scavenging activity and 1f was found to be the most active one against Bacillus dysenteriae.

Synthesis and antiprotozoal activity of 4-arylcoumarins

A large series of 4-arylcoumarins was synthesized by Suzuki-Miyaura cross-coupling reaction and evaluated for antiprotozoal activity against Plasmodium falciparum and Leishmania donovani. Several compounds were found to strongly inhibit the proliferation

VOLUBOLIN, A 4-PHENYL-2H-1-BENZOPYRAN-2ONE FROM DALBERGIA VOLUBILIS

From the ether soluble portion of a methanolic extract of young non-green branches of Dalbergia volubilis, sitosterol, 7-hydroxy-4-methyl-2H-1-benzopyran-2-one, dalbergin, p-hydroxy cinnamic acid, biochanin-A and a new 4-phenylcoumarin, volubolin, have been isolated.The structure of volubolin as 7-hydroxy-4-(3-hydroxy-4-methoxy-phenyl)-2H-1-benzopyran-2-one has been established on the basis of spectral and chemical evidence.Cooccurrence of 4-methyl- and 4-phenyl-coumarins with isoflavones is of biogenetic interest. - Key Word Index: Dalbergia volubilis; Leguminosae; young branches; 7-hydroxy-4-methyl coumarin; dalbergin; biochanin-A; 7-hydroxy-4-(3-hydroxy-4-methoxyphenyl)-2H-1-benzopyran-2-one.
