    Several types of chiral hetero‐ and carbocyclic compounds have been synthesized by using the asymmetric hydrogenation of cyclic alkenes. N,P‐Ligated iridium catalysts reduced six‐membered cyclic alkenes with various substituents and heterofunctionality in good to excellent enantioselectivity, whereas the reduction of five‐membered cyclic alkenes was generally less selective, giving modest enantiomeric
    通过使用环状烯烃的不对称氢化,已经合成了几种类型的手性杂环和碳环化合物。N,P连接的铱催化剂将具有各种取代基和杂官能团的六元环烯烃还原为良好至优异的对映选择性,而五元环烯烃的还原通常选择性较低,给出适度的对映异构体过量。氢化的立体选择性在很大程度上取决于五元环烯烃而不是六元环烯烃的底物结构。六元烯烃还原反应中形成的主要对映异构体可通过选择性模型预测,异构体烯烃具有互补的对映选择性,氢化后可得到相反的旋光异构体。顺式环己烷羧酸盐。
  • Synthesis and olfactory evaluation of optically active β-alkyl substituted γ-lactones and whiskey lactone analogues
    作者:Masashi Kawasaki、Daiki Kato、Takuya Okada、Yuko Morita、Yasuo Tanaka、Naoki Toyooka
    DOI:10.1016/j.tet.2020.130984
    日期:2020.3
    β-alkyl substituted γ-lactones and whiskey lactone analogues were synthesized, and the odor properties were evaluated. During the preparation of the chiral intermediates, we found good reaction conditions for the highly enantioselective esterification of 3-arylmethyl-2-methyl-1-propanols to kinetically resolve them. The results of the olfactory evaluations of the synthesized lactones revealed that the alkyl
    合成了具有光学活性的β-烷基取代的γ-内酯和威士忌内酯类似物,并评估了其气味特性。在手性中间体的制备过程中,我们发现了3-芳基甲基-2-甲基-1-丙醇的高度对映选择性酯化反应的良好反应条件,以动力学方式将它们拆分。合成内酯的嗅觉评价结果表明,γ-内酯环上的烷基对气味分布起重要作用。
  • Total synthesis of (+)-xyloketal D, a secondary metabolite from the mangrove fungus Xylaria sp.

    日期:2004.1
    (+)-Xyloketal D was prepared in a one-pot multistep domino reaction by heating optically active 5-hydroxy-4-methyl-3-methylenepentan-2-one (R) in toluene with 2,4-dihydroxyacetophenone. The absolute configuration of the natural product was confirmed by preparation of the starting enone from a lactone of established absolute configuration. (C) 2003 Elsevier Ltd. All rights reserved.
