  Regioselective opening of epoxy alcohols: mild chemo- and stereoselective preparation of iodohydrins and 1,2-diols

  摘要：

  Several 2,3-epoxy alcohols have been opened, at -60-degrees-C, with MgI2, leading to the corresponding 3-iodo 1,2-diols with a high level of regio- and chemoselectivity. The iodohydrins can be reduced "in situ", by means of nBu3SnH, to the corresponding 1,2-diols. The chemo-, regio-, and stereocontrol of the reaction makes the method of wide use. Furthermore, epoxy alcohol derivatives (acetyl, benzyl, or TBMS) still maintain a strong preference for C-3 attack of the nucleophile. The experimental data strongly suggest that a metal (Mg) centered chelate is formed throughout the reaction, which gives rise to the regioselective delivery of the iodide ion.

  Eu（OTf）3催化的2,3-环氧醇的高区域选择性亲核开环：3取代的1,2-二醇衍生物的有效入口

  摘要：

  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，硫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。

  This article describes a highly effective catalytic asymmetric epoxidation method for olefins using potassium peroxomonosulfate (Oxone, Dupont) as oxidant and a fructose-derived ketone (1) as catalyst. High enantioselectivies have been obtained for trans-disubstituted and trisubstituted olefins which can bear functional groups such as tributylsilyl ether, acetal, chloride, and ester. The enantiomeric

  本文描述了一种使用过一硫酸钾（Oxone，Dupont）作为氧化剂和果糖衍生的酮 (1) 作为催化剂的烯烃高效催化不对称环氧化方法。对于可以带有三丁基甲硅烷基醚、缩醛、氯化物和酯等官能团的反式二取代和三取代烯烃，已经获得了高对映选择性。顺式烯烃和末端烯烃的对映体过量还不高。目前的环氧化反应表明，提高 pH 值后催化剂效率显着提高。机理研究表明，环氧化主要通过螺过渡态进行，这为预测反应的立体化学结果提供了模型。平面过渡态可能是主要的竞争途径。

  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.
