    Design and synthesis of novel FKBP inhibitors
    摘要:
    Small molecule FKBP inhibitors were prepared with inhibitory activity ranging from micromolar to nanomolar. The design of these inhibitors derives from a structural analysis of the substrates for FKBP and cyclophilin. As a consequence of this analysis two key observations were made, namely: (1) amino ketone moieties are suitable as FKBP recognition elements at the P1-P1' site and (2) the P3'-P4' site will accept a trans-olefin as a suitable mimetic of a peptide moiety. The preparation of these non-peptide inhibitors is readily accomplished by a protocol which includes the synthesis of chiral propargylic amines and their subsequent conversion into vinyl zirconium reagents.

  • Cobalt-Catalyzed Reductive Coupling of Activated Alkenes with Alkynes
    作者:Hong-Tai Chang、Thiruvellore Thatai Jayanth、Chun-Chih Wang、Chien-Hong Cheng
    DOI:10.1021/ja073604c
    日期:2007.10.1
    Cobalt complex/Zn systems effectively catalyze the reductive coupling of activated alkenes with alkynes in the presence of water to give substituted alkenes with very high regio- and stereoselectivity in excellent yields. While the intermolecular reaction of acrylates, acrylonitriles, and vinyl sulfones with alkynes takes place in the presence of CoI2(PPh3)2/Zn, the reaction of enones and enals with
    钴络合物/锌系统在水存在下有效地催化活化烯烃与炔烃的还原偶联,以优异的产率得到具有非常高的区域选择性和立体选择性的取代烯烃。虽然丙烯酸酯、丙烯腈和乙烯基砜与炔烃的分子间反应发生在 CoI2(PPh3)2/Zn 存在下,但烯酮和烯醛与炔烃的反应需要使用 CoI2(dppe)/Zn/ZnI2 系统. 活化的烯烃(烯酮、烯醛、丙烯酸酯和丙烯腈)与炔烃的分子内还原偶联也有效。此外,使用该方法制备了多种环内酯和内酰胺。基于在 D2O 存在下进行的氘标记实验,提出了可能的机制途径。

    Mechanisms are proposed to account for evidence indicating that some simple α,β-unsaturated aldehydes and ketones do not react with halogens by the expected attack on the CC bond.

  • A Highly Chemoselective, Diastereoselective, and Regioselective Epoxidation of Chiral Allylic Alcohols with Hydrogen Peroxide, Catalyzed by Sandwich-Type Polyoxometalates:  Enhancement of Reactivity and Control of Selectivity by the Hydroxy Group through Metal−Alcoholate Bonding
    作者:Waldemar Adam、Paul L. Alsters、Ronny Neumann、Chantu R. Saha-Möller、Dorit Sloboda-Rozner、Rui Zhang
    DOI:10.1021/jo0266386
    日期:2003.3.1
    Sandwich-type polyoxometalates (POMs), namely [WZnM2(ZnW9O34)2]q- [M = Mn(II), Ru(III), Fe(III), Pd(II), Pt(II), Zn(II); q = 10-12], are shown to catalyze selectively the epoxidation of chiral allylic alcohols with 30% hydrogen peroxide under mild conditions (ca. 20 degrees C) in an aqueous/organic biphasic system. The transition metals M in the central ring of polyoxometalate do not affect the reactivity
    三明治型多金属氧酸盐(POM),即[WZnM2(ZnW9O34)2] q- [M = Mn(II),Ru(III),Fe(III),Pd(II),Pt(II),Zn(II) ; q = 10-12],表明在温和条件下(约20摄氏度)在水/有机双相体系中,用30%过氧化氢选择性催化手性烯丙醇的环氧化。多金属氧酸盐中心环中的过渡金属M不影响过氧化氢使烯丙醇环氧化的反应性,化学选择性或立体选择性。对于空洞的Keggin POM [PW11O39] 7-,可以观察到相似的选择性,尽管产物收率明显降低,其中过氧钨酸盐络合物已被证明是活性氧化物质。所有这些特征都支持钨过氧配合物,而不是高价过渡金属氧物种作为三明治型POM催化环氧化的关键中间体。通过乙酰化或甲基化将羟基官能团封端时,这些POM未观察到这些羟基保护的底物[1a(Ac)和1a(Me)]的反应性。提出了一种模板来说明反应性和选择性的显着提高,
  • Chemoselective C−H Oxidation of Alcohols to Carbonyl Compounds with Iodosobenzene Catalyzed by (Salen)chromium Complex
    作者:Waldemar Adam、Feyissa Gadissa Gelalcha、Chantu R. Saha-Möller、Veit R. Stegmann
    DOI:10.1021/jo9913457
    日期:2000.4.1
    secondary alcohols with benzylically and allylically activated C-H bonds are chemoselectively oxidized to the corresponding carbonyl compounds by the (salen)Cr(III) complex I as the catalyst and iodosobenzene as the oxygen source; the oxidizing species is the Cr(V) oxo complex. Allylic alcohols with fully substituted double bonds give appreciable amounts of epoxides besides the C-H oxidation products
    通过(salen)Cr(III)配合物I作为催化剂和碘代苯作为氧源,将具有苄基和烯丙基活化的CH键的伯醇和仲醇化学选择性氧化为相应的羰基化合物。氧化物质是Cr(V)氧配合物。具有完全取代的双键的烯丙醇除CH氧化产物烯酮外,还提供相当数量的环氧化物,而饱和醇则不易被氧化。

    chiral allylic alcohols 2 by manganese complexes of the cyclic triamine 1,4,7-trimethyl-1,4,7-triazacyclononane (tmtacn) 1 and hydrogen peroxide as oxygen donor in the presence of co-catalyst are investigated to understand the factors that affect the catalyst selectivity. Chemoselectivity and diastereoselectivity of catalyst 1 are significantly affected by the structure of the allylic alcohol and the
