  • Selective 1,4-Chiral Induction in the Reaction of Enolates Generated from<i>t</i>-Butyl δ-Hydroxy Carboxylates
    作者:Koichi Narasaka、Yutaka Ukaji、Kazutoshi Watanabe
    DOI:10.1246/bcsj.60.1457
    日期:1987.4
    Lithium enolates generated from t-butyl esters of δ-hydroxy carboxylic acids with lithium dialkylamides in THF–HMPA were alkylated stereoselectively to give the corresponding syn-α-alkylated δ-hydroxy esters. The generation of the enolates was accelerated by the addition of lithium trifluoromethanesulfonate, and the successive aldol and hydroxylation reactions of the enolates also proceeded in a stereoselective manner.
    在THF-HMPA体系中,由δ-羟基羧酸的叔丁酯和二烷基锂酰胺生成锂烯醇盐,随后立体选择性地进行烷基化反应,得到相应的顺式-α-烷基化δ-羟基酯。通过添加三氟甲磺酸锂可加速烯醇盐的生成,并且烯醇盐的连续aldol反应和羟基化反应也以立体选择性方式进行。
  • Preparation of Optically Enriched Secondary Alkyllithium and Alkylcopper Reagents—Synthesis of (−)‐Lardolure and Siphonarienal

    日期:2018.5.4
    converted into secondary alkyllithium and secondary alkylcopper compounds with very high retention of configuration. Quenching with various electrophiles, including chiral epoxides, provided a range of chiral molecules with high enantiomeric purity (>90 % ee). This method has been applied in an iterative fashion in the total synthesis of (−)‐lardolure in 13 steps and 5.4 % overall yield (>99 % ee, dr>99:1)
    将光学富集的仲烷基碘化物转化为仲烷基锂和仲烷基铜化合物,并保持很高的构型。用包括手性环氧化物在内的各种亲电试剂进行猝灭,提供了一系列具有高对映体纯度(> 90%ee)的手性分子 。该方法已以迭代方式应用在(-)-lardolure的总合成中,共13步,总收率5.4%(> 99%  ee,dr> 99:1)和siphonarienal在15步中,总收率5.6%( > 99%  ee,dr> 99:1)从市售的(R)-3-羟基丁酸乙酯(> 99%  ee)开始。
  • Stereoselective Synthesis of δ-Lactones from 5-Oxoalkanals via One-Pot Sequential Acetalization, Tishchenko Reaction, and Lactonization by Cooperative Catalysis of Samarium Ion and Mercaptan
    作者:Jue-Liang Hsu、Jim-Min Fang

    日期:2001.12.1
    sequence of acetalization, Tishchenko reaction and lactonization. The deliberative use of mercaptan, by comparison with alcohol, is advantageous to facilitate the catalytic cycle. The reaction mechanism and stereochemistry are proposed and supported by some experimental evidence. Such samarium ion/mercaptan cocatalyzed reactions show the feature of remote control, which is applicable to the asymmetric synthesis
    通过sa离子和硫醇的协同催化,一系列5-氧代烷醛以有效和立体选择性的方式转化为(取代的)δ-内酯。这一一锅法包括一系列缩醛化,Tishchenko反应和内酯化。与醇相比,有意使用硫醇有利于促进催化循环。提出了反应机理和立体化学,并得到了一些实验证据的支持。sa离子/硫醇共催化反应显示出远程控制的特征,适用于旋光性δ-内酯的不对称合成。这项研究还证明了两种昆虫信息素(2S,5R)-2-甲基己内酯和(R)-十六烷内酯的合成,

    A simple and efficient method for the remote (1,4- and/or 1,5-) stereocontrol was realized by utilizing an intramolecular carbonyl reduction with ThexBH2(Thex = 1,1,2-trimethylpropyl).

  • Remote Control of Regio- and Diastereoselectivity in the Hydroformylation of Bishomoallylic Alcohols with Catalytic Amounts of a Reversibly Bound Directing Group
    作者:Christian U. Grünanger、Bernhard Breit
    DOI:10.1002/anie.200905949
    日期:2010.1.25
    Remote and reversible! Phosphinites serve as reversibly bound directing groups for the remote control of the regio‐ and diastereoselective hydroformylation of bishomoallylic alcohols (see scheme; r.r: regioisomer ratio). The distance between the double bond and the functional hydroxy group to which the directing group is reversibly bound is the longest ever reported.
    远程且可逆!次膦酸酯是可逆结合的导向基团,用于远程控制双烯丙基烯丙醇的区域和非对映选择性加氢甲酰化(请参阅方案; rr:区域异构体比率)。双键与可逆结合的方向性羟基基团之间的距离是有史以来最长的。
