    摘要:
    据报道,(-)-多杀菌素A(1)的十氢化物为茚并二烯核12的高度非对映选择性和对映选择性合成。通过实施空间方向群策略,由内酯9的非对映选择性的跨环Diels-Alder反应产生了三环内酯37。然后,使用Ireland-Claisen环收缩37获得了天然产物的三环核。这两个步骤的顺序导致非对映选择性几乎完全丧失。

    Inhibition of collagenase by aranciamycin and aranciamycin derivatives.
    摘要:
    Aranciamycin (1), an anthracycline antibiotic, was found to be an inhibitor of Clostridium histolyticum collagenase, with an IC50 = 3.7 x 10(-7) M. Elastase and trypsin were not inhibited at concentrations less-than-or-equal-to 10(-5) M. A number of aranciamycin derivatives 2-13 were prepared and tested for collagenase inhibition. While loss of activity was found for derivatives modified in the sugar ring or rings B and D of the aglycone, increased potency was found when the tertiary alcohol at C-9 was esterified. All compounds 1-13 were found to inhibit DNA synthesis of Yoshida sarcoma tumor cells.

  • Total Synthesis of Spinosyn A. 2. Degradation Studies Involving the Pure Factor and Its Complete Reconstitution
    作者:Leo A. Paquette、Iván Collado、Mark Purdie
    DOI:10.1021/ja974010k
    日期:1998.3.1
    A total synthesis of natural levorotatory spinosyn A (1) has been achieved. The first objective, to confirm the absolute configurational assignment of tricyclic ketone 2 prepared earlier, was accomplished by oxidative degradation of the macrocyclic lactone ring in 1. The route began with the implementation of a four-step one-pot process that resulted in the efficient conversion of 6 into 18. A combination

    作者:Cosme G. Francisco、Antonio J. Herrera、Ernesto Suárez

    日期:2002.10.1
    for the synthesis of chiral 6,8-dioxabicyclo[3.2.1]octane and 2,7-dioxabicyclo[2.2.1]heptane ring systems under neutral conditions. This reaction can be considered to be an intramolecular glycosidation that goes through an intramolecular hydrogen abstraction promoted by an alkoxy radical followed by oxidation of the transient C-radical intermediate to an oxycarbenium ion. This methodology is useful
