Divergent and concise total syntheses of dihydrochalcones and 5-deoxyflavones recently isolated from Tacca species and Mimosa diplotricha
Dihydrochalcones and 5-deoxyflavones are types of compounds possessing various biologically interesting properties. Herein, we report the concise and divergent total syntheses of several naturally occurring dihydrochalcones and 5-deoxyflavones from readily available starting materials. The divergent strategy is based around manipulation of a common chalcone scaffold and features application of ...
متن کاملFurther Dihydrochalcones from Crotolaria ramosissima
Crotolaria ramosissima is a weed plant belonging to the family Leguminoseae. It is a much branched sticky woody herb. The flowers are yellow tinged with purple. It is distributed in some places of Tamilnadu and coastal areas of Andrha Pradesh. The plant contains waxes, and, when flowering, a yellow exudate appears in the inflorescences. Recently, we published the corrected structure of crotaram...
متن کاملNonnutritive sweeteners: taste-structure relationships for some new simple dihydrochalcones.
Six sweet and five nonsweet simple nonglycosidic dihydrochalcones were prepared, two of which have properties comparable to those of the intensely sweet neohesperidin dihydrochalcone.
متن کاملCytotoxic C-benzylated dihydrochalcones from Uvaria acuminata.
Two new C-benzylated dihydrochalcones, isochamuvaritin (1) and acumitin (2), have been isolated from the African medicinal plant Uvaria acuminata, together with the previously reported benzylbenzoate (3), uvaretin (4), isouvaretin (5), diuvaretin (6), and uvangoletin (7). The structural elucidation of compounds 1 and 2 in spectroscopic studies is described. C-Benzylated dihydrochalcones, especi...
متن کاملAntibacterial flavanones and dihydrochalcones from Macaranga trichocarpa.
Previously we had isolated two prenylated flavanones and two prenylated dihydrochalcones, macatrichocarpins A-D (1-4), from the acetone extract of the leaves of Macaranga trichocarpa. Re-examination of the fractions containing minor components resulted in the isolation of four more flavonoid derivatives, including two new prenylated dihydrochalcones, oxymacatrichocarpin C (5) and isomacatrichoc...
