    Concerning the Efficient Conversion of Epoxy Alcohols into Epoxy Ketones Using Dioxiranes
    摘要:
    Representative epoxy alcohols are cleanly converted into the corresponding epoxy ketones in high yield by selective oxidation using dimethyldioxirane (1a) and its trifluoro analogue (1b) under mild conditions. The oxidation is found to take place leaving the configuration at the epoxy functionality unaffected. The direct oxyfunctionalization of simple cyclic epoxides with the powerful dioxirane 1b provides another attractive method to access epoxy ketones regioselectively.

  • Steric and Electronic Effects in the Diastereoselective Catalytic Epoxidation of Cyclic Allylic Alcohols with Methyltrioxorhenium (MTO)
    作者:Waldemar Adam、Catherine M. Mitchell、Chantu R. Saha‐Möller
    DOI:10.1002/(sici)1099-0690(199904)1999:4<785::aid-ejoc785>3.0.co;2-#
    日期:1999.4
    Good cis selectivity is observed in the epoxidation of the cyclic allylic alcohols 2-cyclopentenol and 2-cyclohexenol due to a hydroxy-directing effect through hydrogen bonding; however, for 2-cycloheptenol and 2-cyclooctenol hydrogen bonding is ineffective and steric interactions cause a higher trans selectivity. The conformationally fixed cis- and trans-5-tert-butyl-2-cyclohexenols serve as suitable
    对于一系列的3-烷基取代的环己烯,已经评估了在用甲基三氧or //过氧化氢加合物(MTO / UHP)进行环氧化时,烯丙基取代基的空间效应。的反式与取代基的大小选择性增加,并且非对映选择性遵循塔夫脱(的立体取代基常数的良好的线性相关性ë小号)或Charton(ν)。由于通过氢键的羟基引导作用,在环状烯丙基醇2-环戊烯醇和2-环己烯醇的环氧化中观察到良好的顺式选择性。但是,对于2-环庚烯醇和2-环辛烯醇,氢键无效,空间相互作用会导致更高的反式选择性。构象固定的顺式和反式-5-叔丁基-2-环己烯醇用作合适的底物,用于测量在这些环氧化反应中的氧转移的过渡态的二面角。因此,MTO / UHP氧化剂有利于一个准赤道有效氢键(羟基-组指向性)的羟基的结构,以类似于米苯甲酸(米-CPBA)和二甲基二(DMD),和一个二面角约。建议130°。

  • 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

    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/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。多属氧酸盐中心环中的过渡属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过氧配合物,而不是高价过渡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,

    DOI:10.1021/ol502264y
    日期:2014.9.5
    In our study of the total synthesis of (+)-irciniastatin A, we found a need to develop a method that enables a C3-selective nucleophilic ring opening of 2,3-epoxy alcohol by MeOH, by which we found that the use of combined catalytic amounts of Eu(OTf)3 and 2,6-di-tert-butyl-4-methylpyridine (DTBMP) enables the intended transformation to obtain 3-methoxy-1,2-diol efficiently. Promising features of a
    在我们对(+)-irciniastatin A的总合成的研究中,我们发现有必要开发一种方法,该方法能够使MeOH对2,3-环氧醇进行C3选择性亲核开环,从而发现使用Eu(OTf)3和2,6-二叔丁基-4-甲基吡啶(DTBMP)的组合催化量能够实现预期的转化,从而有效地获得3-甲氧基-1,2-二醇。描述了使用包括醇,醇和未保护的胺在内的各种亲核试剂实现2,3-和3,4-环氧醇的高度区域选择性亲核开环的方案的有前景的特征。

    intermediates I and II. Whereas intermediate II is responsible for the competitive formation of elemental sulfur, intermediate I, presumably an oxathiirane, is the active sulfur-transferring species. The episulfidation was compared with the epoxidation by the related dimethyldioxirane, and bo...
    噻吩内过氧化物 2 是通过噻吩 1 的光氧化制备的,当在环烯烃存在下热解时,将原子(高达 92%)转移到应变的环烯烃以形成丙烷。非对映异构体对顺式/反式环辛烯 (5b) 进行立体选择性反应,这说明了协调过程,而不是开放的偶极和/或双自由基中间体。还研究了手性环辛烯醇 5c-e 组,并通过化学相关性和 NMR 光谱和 X 射线分析指定了各个杂丙环的相对构型。该过程的一级动力学清楚地表明内过氧化物 2 本身不是转移物质,但它被热转化为中间体 I 和 II。而中间体 II 负责元素的竞争性形成,中间体 I,大概是氧杂杂,是活性转移物质。将环化与相关二甲基二环氧乙烷的环氧化进行了比较,并...
