  • Total synthesis of reblastatin: convenient preparation of coupling partners and scaled assembly
    作者:Chuancai Bian、Rui Yan、Xiaoming Yu
    DOI:10.1016/j.tet.2014.03.020
    日期:2014.5
    Potentially scalable total synthesis of reblastatin was achieved based on Panek's previous study. Novel and convenient synthetic routes were developed for the known C8-C20 and C1-C7 coupling partners. The challenging C8-C20 fragment was prepared from TBS protected (S)-5-(hydroxymethyl)dihydrofuran-2(3H)-one (6) in nine steps (20% overall yield), and the C1-C7 fragment was synthesized from commercially available 3,4,6-tri-O-acetyl-D-glucal (9) in eight steps (35% overall yield). On a larger scale, Panek's eight-step assembly of the target molecule from the two partners was also slightly modified, giving 45 mg reblastatin (19% overall yield) in the first batch synthesis. Notable feature of our study is the settlement of the C14 chirality through a diastereoselective alpha-alkylation of 6 followed by a three-step full reduction of the lactone carboxyl, making vastly available 6 a universally applicable C11-C14 synthon for benzenoid/benzoquinone ansamycins.

  • Studies on the Syntheses of Benzoquinone Ansamycin Antibiotics. Syntheses of the C(5)−C(15) Subunits of Macbecin I, Geldanamycin, and Herbimycin A
    作者:Justin K. Belardi、Glenn C. Micalizio
    DOI:10.1021/ol0607995
    日期:2006.5.1
    [graphics]A general and convergent route to the C(5)-C(15) subunits of the benzoquinone ansamycin antibiotics macbecin I, geldanamycin, and herbimycin A is described. Each subunit is prepared by the stepwise coupling of differentially functionalized aldehydes with a pentenyl dianion equivalent derived from diastereoselective pentynylation and regioselective reductive coupling.
