Isoliquiritigenin [ILG, (E)-1] was readily prepared via the Horner–Wadsworth–Emmons reactions using β-ketophosphonates 5a, b. An improved protocol for the synthesis of (E)-1 via the Claisen–Schmidt condensation was also presented.
利用 β-酮膦酸盐 5a 和 b,通过 Horner-Wadsworth-Emmons 反应轻松制备了异喹硫甙元[ILG,(E)-1]。
