制备方法与用途

简介

1,2-辛二醇是一种无色液体或白色固体,在1330 Pa条件下的沸点为131-132℃。它能与多种有机化学品以任意比例混合,具有良好的配方配伍性。

制备

向反应釜中加入甲酸及过氧化氢,并安装搅拌器和温度计以及高位槽。开启搅拌后,逐步加入1-辛烯,持续搅拌约100分钟后进行减压蒸馏,以去除甲酸和水。接着,在溶液中加入氢氧化钠溶液直至呈碱性,随后进行酯提取。所得的提取液用30%氯化钠洗涤两次,再通过无水硫酸镁脱水处理后进行减压蒸馏。在131℃/1330 Pa条件下收集馏分,即为产品1,2-辛二醇。

    名称:
    Regioselective and Stereospecific Azidation of 1,2- and 1,3-Diols by Azidotrimethylsilane via a Mitsunobu Reaction
    摘要:
    A one-pot regio- and stereospecific azidation reaction of 1,2- and 1,3-diols with azidotrimethylsilane (Me3SiN3) via a Mitsunobu reaction has been achieved. With 1,2- and 1,3-diols, the reaction of triphenylphosphine, diisopropyl azodicarboxylate, and Me3SiN3 in dichloromethane gave regioselective azidation at C-2 and C-3, respectively, in good yield (74-90% combined yield of 1a + 1b or of 2a + 2b). However, application of the same reaction conditions to a 1,4-diol led to the exclusive formation of the cyclic ether. The regioselectivity of this one-pot reaction is influenced by the solvent, the degree of steric bulk at C-2 of the 1,2-diol or at C-3 of the 1,3-diol, and the presence of electron-donating and electron-withdrawing groups near the secondary carbinol carbon. This selectivity is discussed in terms of the mechanistic model proposed by Mathieu-Pelta and Evans (Mathieu-Pelta, I.; Evans, S. A., Jr. J. Org. Chem. 1898, 57, 3409-3413), which involves reaction of the dioxaphospholane intermediate with Me3SiN3 to form oxyphosphonium ions 4 and 5.

  • Scope and Mechanism of the Pt-Catalyzed Enantioselective Diboration of Monosubstituted Alkenes
    作者:John R. Coombs、Fredrik Haeffner、Laura T. Kliman、James P. Morken

    日期:2013.7.31
    The Pt-catalyzed enantioselective diboration of terminal alkenes can be accomplished in an enantioselective fashion in the presence of chiral phosphonite ligands. Optimal procedures and the substrate scope of this transformation are fully investigated. Reaction progress kinetic analysis and kinetic isotope effects suggest that the stereodefining step in the catalytic cycle is olefin migratory insertion

    effect on the reaction time and methanesulfonamide effect. The more polar the intermediate osmate ester, the faster is the reaction without methanesulfonamide and the smaller the accelerating methanesulfonamide effect. Methanesulfonamide had no accelerating effect in the asymmetric dihydroxylation of short chain terminal aliphatic olefins as a result of easier accessibility of terminal osmate ester
    为了获得有关甲磺酰胺在Sharpless不对称二羟基化反应的水解步骤中的作用的信息,在有和没有甲磺酰胺的情况下,将一系列脂族和共轭芳族烯烃进行了二羟基化。这项研究的假设是甲磺酰胺是一种助溶剂,有助于将氢氧根离子从水相转移到有机相。的曲线吨90%比的计算分配系数堵塞P非末端脂族烯烃的中间渗透酸酯的数据显示,中间渗透酸酯的极性对反应时间和甲磺酰胺作用有显着影响。中间膦酸酯的极性越强,没有甲磺酰胺的反应越快,甲磺酰胺的促进作用越小。甲烷磺酰胺在短链末端脂族烯烃的不对称二羟基化中没有促进作用,这是由于末端膦酸酯基团更易于与水相接触的结果。发现共溶剂假说在共轭芳族烯烃的不对称二羟基化反应中无效。在Sharpless不对称二羟基化反应所用的反应条件下,

    The hydrolytic kinetic resolution (HKR) of terminal epoxides, using chiral chromium(III)-salen catalysts based on DIANANE (endo,endo-2,5-diaminonorbornane), was studied. A broad substrate scope was found for the chromium(III)-DIANANE catalysts, and very low loadings (down to 0.05 mol %) were needed to achieve high enantiomeric purities of both the remaining epoxides and the product diols (up to >99 %

    catalysts for highly enantioselective asymmetric cis‐dihydroxylation (AD) of alkenes with broad substrate scope remains a challenge. By employing [FeII(L)(OTf)2] (L=N,N′‐dimethyl‐N,N′‐bis(2‐methyl‐8‐quinolyl)‐cyclohexane‐1,2‐diamine) as a catalyst, cis‐diols in up to 99.8 % ee with 85 % isolated yield have been achieved in AD of alkenes with H2O2 as an oxidant and alkenes in a limiting amount. This “[FeII(L)(OTf)2]+H2O2”

  • A Systematic Study on the Bakers’ Yeast Reduction of 2-Oxoalkyl Benzoates and 1-Chloro-2-alkanones

    The bakers’ yeast reduction of a series of 2-oxoalkyl arenecarboxylates [R(C=O)CH2O(C=O)C6H4-p-X] (1a–f) (R = CH3 to n-C6H13; X = H) and the phenyl-modified derivatives (1g–l) (R = n-C5H11, X = OH, CH3, F, Cl, Br, or I) as well as 1-chloro-2-alkanones R(C=O)CH2Cl (6a–f) (R = CH3 to n-C6H13) were systematically investigated. The substrate specificities, configuration and %ee of the reduction products were found to be highly dependent on the length of the alkyl group (R) and the α substituent. Thus, the benzoates 1a–f gave optically active 2-hydroxyalkyl benzoates (2a–f) (R, configuration, %ee) (a: CH3, S, 99; b: C2H5, S, 98; c: C3H7, S, 26; d: n-C4H9, R, 55; e: n-C5H11, S, 15; f: n-C6H13, S, 63) in 11–91% yields. Among the modification experiments of the phenyl group, 1g–l, the p-iodo substituent markedly increased the ee from 15 to 71%, although the yield was rather lowered (22% yield). The reduction of α-chloro ketones 6a–f also gave optically active 1-chloro-2-alkanols (7a–f) [(R, configuration, %ee) (a: CH3, S, 83; b: C2H5, S, 54; c: C3H7, R, 49; d: n-C4H9, R, 80; e, n-C5H11, R, 65; f, n-C6H13, R, 41)] in 16–69% yields.
    对一系列2-氧代烷基苯甲酸酯[R(C=O)CH2O(C=O)C6H4-p-X](1a-f)(R = CH3 至 n-C6H13;X = H)和苯基修饰衍生物(1g-l)(R = n-C5H11,X = OH、CH3、F、Cl、Br 或 I)以及1-氯-2-烷酮R(C=O)CH2Cl(6a-f)(R = CH3 至 n-C6H13)的面包酵母还原进行了系统研究。发现底物特异性、构型和还原产物的%ee高度依赖于烷基链的长度(R)和α取代基。因此,苯甲酸酯1a-f得到了光学活性的2-羟基烷基苯甲酸酯(2a-f)(R,构型,%ee)(a:CH3,S,99;b:C2H5,S,98;c:C3H7,S,26;d:n-C4H9,R,55;e:n-C5H11,S,15;f:n-C6H13,S,63),产率为11-91%。在苯基修饰实验中,1g-l,碘取代基显著提高了ee值,从15%增加到71%,尽管产率明显下降(产率22%)。α-氯代酮6a-f的还原也得到了光学活性的1-氯-2-烷醇(7a-f)[(R,构型,%ee)(a:CH3,S,83;b:C2H5,S,54;c:C3H7,R,49;d:n-C4H9,R,80;e,n-C5H11,R,65;f,n-C6H13,R,41)],产率为16-69%。
