    摘要:
    描述了通过铑催化的取代烯基异氰酸酯和末端炔烃的 [2+2+2] 环加成反应,对映选择性合成带有季取代立体中心的吲哚里西啶。该反应使用脂肪族炔烃提供内酰胺产物,而芳基炔烃产生乙烯基酰胺产物。通过亚磷酰胺配体的修饰,两种产物都获得了高水平的对映选择性、区域选择性和产物选择性。

    Silver-Catalyzed Radical Phosphonofluorination of Unactivated Alkenes
    摘要:
    We report herein a mild and catalytic phosphonofluorination of unactivated alkenes. With catalysis by AgNO3, the condensation of various unactivated alkenes with diethyl phosphite and Selectfluor reagent in CH2Cl2/H2O/HOAc at 40 degrees C led to the efficient synthesis of beta-fluorinated alkylphosphonates with good stereoselectivity and wide functional group compatibility. A mechanism involving silver-catalyzed oxidative generation of phosphonyl radicals and silver-assisted fluorine atom transfer is proposed.

  • Enantioselective Organocatalyzed Bromolactonizations: Applications in Natural Product Synthesis
    作者:Marius Aursnes、Jørn E. Tungen、Trond V. Hansen
    DOI:10.1021/acs.joc.6b01375
    日期:2016.9.16
    The best catalyst enabled the cyclization of several 5-arylhex-5-enoic acids into the corresponding bromolactones with up to 96% ee and in high to excellent chemical yields. The reported catalysts are prepared in a straightforward manner in two steps from dimethyl squarate. The utility of the developed protocol was demonstrated in highly enantioselective syntheses of the sesquiterpenoids (−)-gossoronol
    在10种手性方酰胺氢键键合有机催化剂的存在下,对δ-不饱和羧酸的不对称溴化反应进行了研究。最好的催化剂可以使几种5-芳基己基-5-烯酸环化成相应的溴内酯,其ee最高可达96%,化学产率高至优异。所报道的催化剂是由直方的,由二甲基二甲酸酯分两步制备的。倍半萜类(-)-棉酚和(-)-boivinianin B的高度对映体选择性合成证明了开发方案的实用性。两种天然产物均以≥99%的对映体过量获得。
  • Achiral Counterion Control of Enantioselectivity in a Brønsted Acid-Catalyzed Iodolactonization
    作者:Mark C. Dobish、Jeffrey N. Johnston
    DOI:10.1021/ja301858r
    日期:2012.4.11
    Highly enantioselective halolactonizations have been developed that employ a chiral proton catalyst-N-iodosuccinimide (NIS) reagent system in which the Brønsted acid is used at catalyst loadings as low as 1 mol %. An approach that modulates the achiral counterion (equimolar to the neutral chiral ligand-proton complex present at low catalyst loadings) to optimize the enantioselection is documented for
    已经开发出高度对映选择性卤内酯化反应,它采用手性质子催化剂-N-碘代琥珀酰亚胺 (NIS) 试剂系统,其中布朗斯台德酸以低至 1 mol% 的催化剂负载量使用。在该转化中首次记录了一种调节非手性抗衡离子(与低催化剂负载下存在的中性手性配体-质子复合物等摩尔)以优化对映体选择的方法。通过这种方式,使用市售 NIS 将不饱和羧酸以高产率(高达 98% ee)转化为 γ-内酯。
  • Enantioselective Bromolactonization Using an<i>S</i>-Alkyl Thiocarbamate Catalyst
    作者:Xiaojian Jiang、Chong Kiat Tan、Ling Zhou、Ying-Yeung Yeung
    DOI:10.1002/anie.201202079
    日期:2012.7.27
    The apple never falls far from the tree: S‐alkyl thiocarbamate 1 (see scheme, NBP=N‐bromophthalimide) was prepared in high yield through a synthetic sequence involving a Newman–Kwart rearrangement of the corresponding O‐alkyl thiocarbamates. Compound 1 was used to catalyze bromolactonization, thus providing enantioenriched δ‐lactones in excellent yield and enantioselectivity.
    苹果永远不会离树太远:通过涉及相应的O-烷基硫代氨基甲酸酯的Newman-Kwart重排的合成序列,以高收率制备了S-烷基硫代氨基甲酸酯1(参见方案,NBP = N-溴邻苯二甲酰亚胺)。化合物1用于催化溴化内酯化,从而以优异的收率和对映选择性提供了对映体富集的δ-内酯。
  • Organoselenium Accelerated Bromolactonization Reaction
    作者:Jørn E. Tungen、Renate Kristianslund、Anders Vik、Trond V. Hansen
    DOI:10.1021/acs.joc.9b01294
    日期:2019.9.20
    A highly efficient and regioselective bromolactonization protocol is reported. The quantitative formation of synthetically versatile bromolactones occurs in the presence of only 0.1 mol % of an organoselenium compound, coined DECAD herein, within 90 min. DECAD is conveniently prepared on multigram scale from cheap racemic camphor. The presented protocol was easy to scale up and performed equally well
    据报道,一种高效且区域选择性的溴化内酯化方案。合成通用的溴内酯的定量形成是在90分钟内,仅存在0.1 mol%的有机硒化合物(在本文中称为DECAD)的情况下发生的。DECAD是从便宜的外消旋樟脑以克为单位方便地制备的。所提出的协议易于扩展,并且在克规模上表现同样出色。对该机理的研究表明,DECAD原位形成了硒烯。
  • Tertiary Aminourea-Catalyzed Enantioselective Iodolactonization
    作者:Gemma E. Veitch、Eric N. Jacobsen
    DOI:10.1002/anie.201003681
    日期:——
    Binding the anion: A highly enantioselective iodolactonization of 5‐hexenoic acids has been achieved using a tertiary aminourea‐catalyst (see scheme). The use of catalytic iodine in this process is critical to enhancing both the reactivity and enantioselectivity of the stoichiometric I+ source. The mechanism is proposed to involve binding of an iodonium imidate intermediate by the H‐bond donor catalyst
    结合阴离子:使用叔氨基脲催化剂实现了 5-己烯酸的高度对映选择性碘内酯化(参见方案)。在该过程中使用催化碘对于提高化学计量 I +源的反应性和对映选择性至关重要。该机制被认为涉及通过氢键供体催化剂结合亚胺酸碘鎓中间体。
