Manuifolin Q, an unusual 4-aryl-substituted isoflavan from Maackia tenuifolia.[Pubmed: 14989380]
Manuifolin Q (1), an unusual 4-aryl-substituted isoflavan, was isolated from the roots of Maackia tenuifolia. Its absolute configuration was determined as (3R,4R)-3,4-trans-7,2'-dihydroxy-4'-methoxy-4-[(2,4-dihydroxy-5-(1,1-dimethyl-2-propenyl)]-phenyl-isoflavan, on the basis of spectroscopic analysis.
Manuifolins D, E, and F: new isoflavonoids from Maackia tenuifolia.[Pubmed: 9322365]
Chemical examination of roots of Maackia tenuifolia yielded three new isoflavans, manuifolins D, E, and F, along with the known (6aR, 12aR)-pterocarpin and (6aR,12aR)-maackiain. The new compounds were established as (3R)-5'-(1,1-dimethyl-2-propenyl)-4'- O-(3-methyl-2-butenyl)- 7,2'-dihydroxyisoflavan (1), (3R)-6,5'-bis(1,1-dimethyl-2-propenyl)-7,2',4', -trihydroxyisoflavan (2), and (3R)-5'-(1-isopropylethenyl)-8-(3-methyl-2-butenyl)-7,2',4'- trihydroxyisoflavan (3), respectively, by spectroscopic methods.
