  • Total Synthesis of Leustroducsin B
    作者:Kazuyuki Miyashita、Tomoyuki Tsunemi、Takafumi Hosokawa、Masahiro Ikejiri、Takeshi Imanishi

    Leustroducsin B was synthesized via a convergent route based on division of the leustroducsin molecule into three segments A, B, and C. Two coupling reactions (Julia coupling reaction and Nozaki-Hiyama-Kishi (NHK) reaction) were employed for coupling of segments A and 13: segment A, for the Julia coupling reaction was prepared by a combination of Sharpless asymmetric epoxidation and an epoxide-cleavage reaction with an organoaluminum reagent, while segment A, for the NHK reaction was synthesized from optically active alcohol that had previously been prepared by lipase-catalyzed kinetic resolution. Segment B, whose structure was modified with some functional groups, was synthesized from (R)-malic acid by a combination of Wittig reaction and Sharpless asymmetric dihydroxylation, and segment C, containing a cyclohexane moiety, was prepared by asymmetric Diels-Alder reaction. Segment B was first coupled with segment A, via the Julia coupling reaction, but the yield was low due to unexpected epimerization. The NHK reaction of segment A2 proceeded to give the coupling product in good yield. This product was coupled with segment C via Wittig and Stille coupling reactions, and finally, phosphorylation was carried out by partial hydrolysis of a cyclic phosphate to give leustroducsin B.

    作者:Hayao Matsuhashi、Kousei Shimada

    日期:2002.7
    Chemical transformation of Leustroducsin H to Leustroducsin B has been successfully accomplished in 11 steps including enzymatic hydrolysis of phosphate ester. The process described here enables to differentiate all hydroxyl groups, amino and phosphate functionality so that this process would serve as a useful template for the preparation of whole different kinds of synthetic derivatives in structure
    Leustroducsin H到Leustroducsin B的化学转化已成功完成11个步骤,包括酶促水解磷酸酯。此处描述的方法能够区分所有羟基,氨基和磷酸酯官能度,因此该方法将用作结构活性关系研究中制备各种不同种类合成衍生物的有用模板。通过Akasaka方法将侧链羧酸的绝对构型确定为(S)构型。
