  • 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、 、F、Cl、Br 或 I)以及1--2-烷酮R(C=O)CH2Cl(6a-f)(R = 至 n- )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: ,S,99;b:C2H5,S,98;c:C3H7,S,26;d:n-C4H9,R,55;e:n- ,S,15;f:n- ,S,63),产率为11-91%。在苯基修饰实验中,1g-l,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-代酮6a-f的还原也得到了光学活性的1--2-烷醇(7a-f)[(R,构型,%ee)(a: ,S,83;b: ,S,54;c: ,R,49;d:n- ,R,80;e,n- ,R,65;f,n- ,R,41)],产率为16-69%。
  • Synthesis of Optically Active β,γ-Unsaturated α-Amino Acids and of α,β-Unsaturated γ-Amino Acids. SN2- vs. SN2’-Dichotomy of the Mitsunobu Amination of Allylic Alcohols
    作者:Johann Mulzer、Günther Funk
    DOI:10.1055/s-1995-3847
    日期:1995.1
    Novel and efficient syntheses (6-9 steps, overall yields 10-30%) are described for optically pure β,γ-unsaturated α-amino acids and α,β-unsaturated γ-amino acids, starting from (R)-isopropylidene glyceraldehyde and ethyl (S)-lactate, respectively. The key step is the Mitsunobu reaction of chiral secondary allylic alcohols with phthalimide as the nucleophile, where α,γ allylic transpositions are observed for the first time. The structure-α,γ-ratio-relationship is studied and also the stereochemistry of the allylic transposition. The α-substitution proceeds via clean SN2 inversion, whereas the γ-substitution corresponds to an (E)-anti attack of the nucleophilic with varying stereoselectivities.
    本文描述了从(R)-异丙叉甘油醛和乙基(S)-乳酸分别合成光学纯的β,γ-不饱和α-氨基酸和α,β-不饱和γ-氨基酸的新颖且高效的方法(总步骤为6-9步,总收率为10-30%)。关键步骤是手性仲烯丙醇酰亚胺作为亲核试剂的 Mitsunobu 反应,首次观察到α,γ 烯丙基重排现象。研究了结构-α,γ 比例关系以及烯丙基重排的立体化学。α-取代过程通过干净的 SN2 反转进行,而γ-取代对应于亲核试剂的(E)-反向攻击,具有不同的立体选择性。

    A kinetic resolution of 1,2-diols bearing both a secondary and a primary alcohol motif through an N-heterocyclic carbene-catalyzed oxidative acylation reaction has been developed. A site- and enantioselective esterification reaction is involved for this process. Both the monoacylated diols obtained and the remaining enantioenriched 1,2-diols are versatile building blocks for the preparation of functional

  • The bakers' yeast reductions of α- and β-keto ester derivatives in the presence of a sulfur compound
    作者:Ryuuichirou Hayakawa、Kazumi Nozawa、Kimihiko Kimura、Makoto Shimizu
    DOI:10.1016/s0040-4020(99)00373-7
    日期:1999.6
    enhancement of the reactivity were achieved in the bakers' yeast reduction of the α- and β-keto ester derivatives by the addition of a sulfur compound. High enantioselectivity in the bakers' yeast reduction of keto esters was accomplished by using combination of an addition of a sulfur compound with an appropriate selection of the alcohol part of the ester.
