Synthesis of structurally diverse biflavonoids

Tetrahedron, 2018
Abstract Synthetic biflavonoids are associated with interesting biological activities, yet they remain poorly explored within drug discovery. Recent years have witnessed a growing interest in synthetic approaches that can provide access to structurally novel biflavonoids so that the biological usefulness of this compound class can be more fully ...

Aryllead triacetates as synthons for the synthesis of biflavonoids. Part 2. Synthesis of a Garcinia-type biflavonoid

Journal of the Chemical Society, Perkin Transactions 1, 1994
Arylation of 3-(phenylsulfonyl)chroman-4-one 1 with simple aryllead triacetates affords the corresponding 3-aryl-3-(phenylsulfonyl)chroman-4-one in 64–74% yield. However, no reaction took place with the hindered 2,4,6-trimethoxyphenyllead triacetate 9. Reaction of the 8-triacetoxyplumbylflavane derivative 10 with 4′-methoxy-3-(phenylsulfanyl)flavanone ...

A biflavonoid from Garcinia nervosa

Phytochemistry, 1988
Abstract A new biflavonoid has been isolated from the leaves of Garcinia nervosa . Its structure I-5, II-5, I-7, II-7, I-3′, I-4′, II-4′-heptahydroxy-[I-3, II-8]-flavanonylflavone was elucidated with the help of chemical and spectral methods.
