This paper describes the first successful synthesis of two isoflavone bis-C-glycosides, genistein and orobol 6,8-di-C-β-D-glucopyranosides from phloroacetophenone bis-C-glycoside in total yields of 27 and 19%, respectively, using a four-step reaction: dir

Synthesis of racemates of the complex pyranoisoflavan, (3S)-heminitidulan, a metabolite from the bark of Dalbergia nitidula, is accomplished.The isoflavone C-glycoside pairs 8-C-β-D-glucopyranosyl- and 6,8-di-C-β-glucopyranosyl-genistein and -orobol and the associated rotenoid glycoside (5'R,6aR,12aR)-8'-O-β-D-glucopyranosyl-12a-hydroxyamorphigenin comprise the predominant isoflavonoids in the same source. 13C N.m.r. spectra of the glycosides are recorded.
