Rotenoids from Amorpha canescens

Transactions of the Kansas Academy of Science (1903-), 1979
recovered no rotenoids. Elution (6-8 column volumes) with 1:3 EtOAc/hexane recovered all rotenoid materials. The solvent was evaporated and the residue analyzed by TLC (Delfel, 1966) and HPLC (Moring, 1977). Direct comparison with standards suggested the presence of rotenone, degulin, tephrosin, and rotenolone. Peaks with retention volumes of rotenone,

Rotenoids from roots of Clitoria Fairchildiana

Phytochemistry, 1998
A new rotenoid, named 9-demethylclitoriacetal, together with the known compounds, 11-deoxyclitoriacetal, 6-deoxyclitoriacetal, clitoriacetal and stemonal, was isolated from roots of Clitoria fairchildiana. Its structure was elucidated as 6a,12a-dihydro-6,9,11,12a-tetrahydroxy-2,3-dimethoxy-[1]benzopyrano[3,4-b] [1]benzopyran-12(6H)-one (1), on the ...

NMR investigations of rotenoids

Tetrahedron, 1973
Abstract Extensive NMR studies of major rotenoids have (1) verified the cis B/C ring fusion of rotenone; (2) confirmed the structure of the reduction-dehydration product of rotenone; (3) provided considerable evidence regarding the preferred conformations of rotenoids; (4) revealed an array of long-range couplings; and (5) pointed up analytically ...

Optical resolution of rotenoids

Journal of Heterocyclic Chemistry, 1987
AbstractOptical resolution of selected rotenoids containing 1‐3 asymmetric centers in dihydrobenzopyranofuroben‐zopyranone and dihydrobisbenzopyranopyranone series has been achieved on two chiral high‐performance liquid chromatographic (hplc) stationary phases.

Novel N-containing rotenoid and seco-rotenoid from the root of Derris elliptica

Journal of Asian Natural Products Research, 2009
Two new rotenoids, 2-hydroxy-5-aminorotenonone (1) and elliptoic acid (2), were isolated from the roots of Derris elliptica collected in Guangdong Province, China. Their structures were established by extensive spectral analysis. Compound 1 is the first N-containing rotenoid and compound 2 is the third rotenoid with the cleavage of C(12)-C(12a).

Rotenoid synthesis via radical cyclisation

Journal of the Chemical Society, Chemical Communications, 1988
The (±)-6aα, 12aα, 12α-chromanochromanol acetate (11; R = Ac), representing the core structure of the insecticidal rotenoid alcohol (2), has been synthesised in six steps from the chromone (4); the cis,cis-stereochemistry is obtained in an intramolecular 6-exo aryl radical addition.
