    手性亲核催化剂 TADMAP [1, 3-(2,2,2-三苯基-1-乙酰氧基乙基)-4-(二甲氨基)吡啶]已由 3-锂硫-4-(二甲氨基)吡啶 (5) 和三苯乙醛 (3),然后进行酰化和拆分。TADMAP 催化恶唑基、呋喃基和苯并呋喃基烯醇碳酸酯的羧基迁移,具有良好到极好的对映选择水平。恶唑反应特别有效,用于制备含有季不对称碳的手性内酰胺 (23) 和内酯 (30)。吲哚系列中 TADMAP 催化的羧基迁移相对较慢,并且具有不一致的对映选择性。建模研究 (B3LYP/6-31G*) 已用于定性关联催化剂构象、反应性和对映选择性。

  • A Dual-Catalysis Approach to the Asymmetric Steglich Rearrangement and Catalytic Enantioselective Addition of <i>O</i>-Acylated Azlactones to Isoquinolines
    作者:Chandra Kanta De、Nisha Mittal、Daniel Seidel
    DOI:10.1021/ja208156z
    日期:2011.10.26
    A dual-catalysis approach, namely the combination of an achiral nucleophilic catalyst and a chiral anion-binding catalyst, was applied to the Steglich rearrangement to provide α,α-disubstituted amino acid derivatives in a highly enantioselective fashion. Replacement of the nucleophilic co-catalyst for isoquinoline resulted in a divergent reaction pathway and an unprecedented transformation of O-acylated
    双催化方法,即非手性亲核催化剂和手性阴离子结合催化剂的组合,应用于 Steglich 重排,以高度对映选择性的方式提供 α,α-二取代氨基酸生物。替代异喹啉的亲核助催化剂导致了不同的反应途径和 O-酰化吖内酯的前所未有的转化。该策略提供了高度取代的 α,β-二氨基酸生物,具有出色的立体控制平。
  • Synthesis and Catalytic Properties of 4-Aryl-2,3-dihydro-4<i>H</i>-pyrimido[2,3-<i>b</i>]benzothiazoles for Asymmetric Acyl or Carboxyl Group Transfer Reactions
    作者:Baby Viswambharan、Tatsuya Okimura、Satoko Suzuki、Sentaro Okamoto

    日期:2011.8.19
    4-Aryl-2,3-dihydro-4H-pyrimido[2,3-b]benzothiazoles (4-Ar-DHPBs) were synthesized and their catalytic activity and selectivity in kinetic resolution of a secondary alcohol as well as in the Steglich rearrangement and related reactions were evaluated. 4-Aryl-DHPBs showed low enantioselectivity in the acylative kinetic resolution of 1-phenylethanol. Conversely, they catalyzed the Steglich rearrangement
    合成了4-Aryl-2,3-dihydro-4 H -pyrimido [2,3- b ]苯并噻唑(4-Ar-DHPBs),它们在仲醇动力学和Steglich动力学拆分中具有催化活性和选择性重排和相关反应进行了评估。4-芳基-DHPB在1-苯基乙醇的酰基动力学拆分中显示出低的对映选择性。相反,他们以适中至优异的对映选择性催化了Steglich重排,证明了通过在DHPB的4位上引入取代基进行远程立体控制的可能性。
  • Organic base effects in NHC promoted O- to C-carboxyl transfer; chemoselectivity profiles, mechanistic studies and domino catalysis
    作者:Craig D. Campbell、Christopher J. Collett、Jennifer E. Thomson、Alexandra M. Z. Slawin、Andrew D. Smith
    DOI:10.1039/c1ob05160a
    日期:——
    The O- to C-carboxyl transfer of oxazolyl carbonates promoted by triazolinylidenes, generated in situ with NEt3, shows a markedly different rate and chemoselectivity profile to the same reaction promoted by triazolinylidenes generated using KHMDS. The mechanism of these pathways has been probed through extensive crossover studies to understand this process. The use of NEt3 as a base allows domino multi-step
    由NEt 3原位产生的由三唑啉亚基促进的碳酸恶唑碳酸酯的O - C羧基转移与由KHMDS生成的三唑啉亚基促进的相同反应显示出明显不同的速率和化学选择性。通过广泛的交叉研究探索了这些途径的机制,以了解这一过程。尽管手性NHC在这些多米诺反应过程中仅产生适度平的不对称诱导(<15%ee),但使用NEt 3作为碱基可以开发出多米诺骨牌多步反应序列。

    DOI:10.1039/c6sc02646j

    A pseudo-enantiomeric pair of optically switchable helicenes containing a catalytic 4-N-methylaminopyridine (MAP) bottom unit and a C2-symmetric, (10R,11R)-dimethoxymethyl-dibenzosuberane top template was synthesized. They underwent complementary photoswitching at 290 nm (P/M′, <1/>99) and 340 nm (P/M′, 91/9) and unidirectional thermo-rotation at 130 °C (P/M′, >99/<1). They were utilized to catalyze

  • Probing the Efficiency of N-Heterocyclic Carbene Promoted <i>O</i>- to C-Carboxyl Transfer of Oxazolyl Carbonates
    作者:Jennifer E. Thomson、Craig D. Campbell、Carmen Concellón、Nicolas Duguet、Kathryn Rix、Alexandra M. Z. Slawin、Andrew D. Smith
    DOI:10.1021/jo702720a
    日期:2008.4.1
    Screening of a range of azolium salts, bases and solvents for reactivity indicates that triazolinylidenes, generated in situ with KHMDS in THF, promote the Steglich rearrangement of oxazolyl carbonates with high catalytic efficiency (typical reaction time 5 min at < 1.5 mol % NHC). This protocol shows wide substrate applicability, even allowing the efficient generation of vicinal quaternary centers. An improved experimental procedure is also described that allows a simplified one-pot reaction protocol to be employed with similarly high catalytic efficiency.
