The first total synthesis of the pyranoisoflavone kraussianone 1 (1) is described. The key steps involved the Suzuki−Miyaura reaction for the construction of the isoflavone core and the regioselective formation of the dimethylpyran scaffolds to the phloroglucinol (ring A) and resorcinol (ring B) moieties of kraussianone 1 (1). This route also provided access to the related isoflavones eriosemaone D

Genistein was efficiently synthesized from (2,4,6-trihydroxyphenyl)ethanone by a novel five-step procedure involving the formation of an enamino ketone, followed by ring closure and a Suzuki coupling reaction using palladium acetate and poly(ethylene glycol).
