  • Enantioselective Synthesis of α-<i>exo</i>-Methylene γ-Butyrolactones via Chromium Catalysis
    作者:Weiqiang Chen、Qin Yang、Tian Zhou、Qingshan Tian、Guozhu Zhang
    DOI:10.1021/acs.orglett.5b02597
    日期:2015.11.6
    obtained via a two-step sequence consisting of a highly enantioselective chromium-catalyzed carbonyl 2-(alkoxycarbonyl)allylation and lactonization. A variety of functional groups are compatible under the mild reaction conditions. The synthetic utility of this methodology was demonstrated by two short derivatization transformations and the enantioselective synthesis of (+)-methylenolactocin.
    通过两步序列获得了对映体富集的α-外-亚甲基γ-丁内酯,该过程由高度对映体选择性的铬催化的羰基2-(烷氧基羰基)烯丙基化和内酯化组成。在温和的反应条件下,各种官能团是相容的。该方法的合成效用通过两次短暂的衍生化转化和(+)-甲基烯醇内酯的对映选择性合成得到证明。
  • Enantiodivergent synthesis of (−)-methylenolactocin and (+)-methylenolactocin from d-mannitol
    作者:Manju Ghosh、Sritama Bose、Soumitra Maity、Subrata Ghosh
    DOI:10.1016/j.tetlet.2009.10.011
    日期:2009.12
    An enantiodivergent synthesis of both enantiomers of methylenolactocin is described through stereocontrolled addition of n-pentyl magnesium bromide to two d-mannitol-derived diastereomerically related aldehydes having an α-chiral center with a β hetero atom.
    通过将正戊基溴化镁立体控制地加成到两个具有α-手性中心且带有β杂原子的与d-甘露醇衍生的非对映异构相关的醛中,描述了甲基烯醇内酯的两个对映体的对映异构体合成。
  • Enantioselective Butenolide Preparation for Straightforward Asymmetric Syntheses of γ-Lactones – Paraconic Acids, Avenaciolide, and Hydroxylated Eleutherol
    作者:Stefan Braukmüller、Reinhard Brückner
    DOI:10.1002/ejoc.200500961
    日期:2006.5
    occurring γ-lactones (+)-methylenolactocin (13) and its enantiomer, (+)-protolichesterinic acid (14) and its enantiomer, (+)-rocellaric acid (15), and the methylene bis(γ-lactone) ()-avenaciolide (16) were synthesized with 95–98 % ees in very few steps. Enantiocontrol was imposed by the asymmetric dihydroxylation of trans-configured β,γ-unsaturated carboxylic esters (namely compounds 1i, 1j, and 1n)
    天然存在的 γ-内酯 (+)-亚甲基乳酸菌素 (13) 及其对映体、(+)-protolichesterinic acid (14) 及其对映体、(+)-rocellaric acid (15) 和亚甲基双(γ-内酯) (-)-avenaciolide (16) 是通过很少的步骤合成的,具有 95-98% 的 ee。对映控制是由反式构型的 β,γ-不饱和羧酸酯(即化合物 1i、1j 和 1n)与 AD mix-α® [对于左旋目标结构,除了 (-)-avenaciolide 外] 或AD mix-β® [用于右旋目标结构加 (-)-avenaciolide]。β,γ-不饱和羧酸酯 1e 需要更多的氧化剂和助剂来生产羟基内酯 R,R-3e,它是萘并-γ-内酯 (+)-9-羟基戊二烯的前体 (12; 96 % ee) .

    A collective synthesis of a γ-butyrolactone class of paraconic acids such as (+)-methylenolactocin, (+)-phaseolinic acid, (+)-nephrosteranic acid, (+)-nephrosterinic acid, (+)-rocellaric acid and (+)-protolichesterinic acid is described. The strategy adopted is protecting-group-free based on efficient Pd-catalyzed Suzuki–Miyaura coupling and Ru-catalyzed Sharpless oxidation to construct the core β

    作者:Kuheli Chakrabarty、Ivana Defrenza、Nunzio Denora、Sara Drioli、Cristina Forzato、Massimo Franco、Giovanni Lentini、Patrizia Nitti、Giuliana Pitacco
    DOI:10.1002/chir.22419
    日期:2015.12
    enantiomers of three biologically relevant paraconic acids—MB‐3, methylenolactocin, and C75—were obtained with enantioselectivities up to 99% by kinetic enzymatic resolutions. Good enantiomeric excesses were obtained for MB‐3 and methylenolactocin, using α‐chymotrypsin and aminoacylase as enantiocomplementary enzymes, while C75 was resolved with aminoacylase. They all were evaluated for their antiproliferative
    通过动力学酶拆分,获得了三种生物学上相关的对锥酸(MB-3,甲基内酯和C75)的两种对映体,其对映体选择性高达99%。使用α-胰凝乳蛋白酶和氨酰酶作为对映体互补酶,MB-3和甲基内酯都获得了良好的对映体过量,而C75则用氨酰酶进行拆分。对它们的抗增殖,抗菌和抗真菌活性进行了评估,显示出弱的作用,并且在每种情况下对映体之间几乎没有区别。在高浓度(16–64 µg / mL)下,(–)‐ C75可以作为革兰氏阳性菌的抗菌剂。手性27:239–246,2015。©2015 Wiley Periodicals,Inc.
