  • Ir-catalysed allylic substitution: mechanistic aspects and asymmetric synthesis with phosphorus amidites as ligands
    作者:Björn Bartels、Günter Helmchen
    DOI:10.1039/a900864k
    日期:——
    Ir-catalysed allylic alkylations of enantiomerically enriched monosubstituted allylic acetates proceed with up to 79% retention of configuration using P(OPh)3 as ligand; further evidence supports the assumption of σ-allyl complexes as intermediates, and high regio- and enantioselectivity in asymmetric allylic alkylations of achiral or racemic substrates is achieved with phosphorus amidites as ligands.
    铱催化的富集单取代烯丙基乙酸酯的手性保持烯丙基烷基化反应,使用P(OPh)3作为配体,保持配置率高达79%;进一步证据支持σ-烯丙基复合物为中间体的假设,并且使用磷酰亚胺作为配体,可在非手性或外消旋底物的烯丙基烷基化反应中实现高程度的区域和立体选择性。
  • Iridium-Catalysed Allylic Substitution: Stereochemical Aspects and Isolation of IrIII Complexes Related to the Catalytic Cycle
    作者:Björn Bartels、Cristina García-Yebra、Frank Rominger、Günter Helmchen
    DOI:10.1002/1099-0682(200210)2002:10<2569::aid-ejic2569>3.0.co;2-5
    日期:2002.10
    Ir-catalysed allylic alkylations of enantiomerically enriched monosubstituted allylic acetates proceed with up to 87% retention of configuration using P(OPh)3 as ligand. High regio- and enantioselectivity of up to 86% ee in asymmetric allylic alkylations of achiral or racemic substrates is achieved with monodentate phosphorus amidites as ligands. Lithium N-tosylbenzylamide was identified as a suitable
    使用 P(OPh)3 作为配体,Ir 催化的烯丙基烷基化对映体富集的单取代烯丙基乙酸酯的构型保留率高达 87%。以单齿磷酰胺作为配体,在非手性或外消旋底物的不对称烯丙基烷基化中实现了高达 86% ee 的高区域和对映选择性。N-tosylbenzylamide 锂被确定为适合烯丙基胺化的亲核试剂。特别重要的是使用氯化锂作为添加剂,通常会导致对映选择性增加。通过 X 射线晶体结构分析和光谱数据对两种 (π-烯丙基) IrIII 配合物进行了表征。
  • Allyl 4-Chlorophenyl Sulfone as a Versatile 1,1-Synthon for Sequential α-Alkylation/Cobalt-Catalyzed Allylic Substitution
    作者:Masahiro Kojima、Shigeki Matsunaga、Tomoyuki Sekino、Shunta Sato、Kazuki Kuwabara、Koji Takizawa、Tatsuhiko Yoshino
    DOI:10.1055/s-0040-1707524
    日期:2020.7
    rare 1,1-dipole synthons, allyl sulfones are rarely used in target-oriented syntheses, likely due to the lack of a general catalytic method for their branch-selective allylic substitution. Herein, we identified allyl 4-chlorophenyl sulfone as a versatile linchpin for both base-mediated α-derivatization and subsequent cobalt-catalyzed allylic substitution. The sequential transformations allow for highly
    尽管烯丙基砜具有罕见的1,1-偶极合成子的独特潜力,但很少用于目标导向的合成中,这可能是由于缺乏用于支链选择性烯丙基取代的通用催化方法。在这里,我们确定了烯丙基4-氯苯基砜作为通用介导的碱介导的α-衍生化和随后的钴催化的烯丙基取代。连续转化允许高度区域选择性地获得具有多种脂族侧链的支链烯丙基取代产物。与传统的金属催化方案相比,光氧化还原使能的钴催化对于实现高产率和区域选择性的脱磺酰基取代是必不可少的,而传统的金属催化方案在相应的转化中导致了较差的结果。
  • Ir-catalyzed asymmetric allylic alkylation using chiral diaminophosphine oxides: DIAPHOXs. Formal enantioselective synthesis of (−)-paroxetine
    作者:Tetsuhiro Nemoto、Tatsurou Sakamoto、Takashi Fukuyama、Yasumasa Hamada
    DOI:10.1016/j.tetlet.2007.05.120
    日期:2007.7
    An Ir-catalyzed asymmetric allylic alkylation using chiral diaminophosphine oxide is described. Asymmetric allylic alkylation of terminal allylic carbonates proceeded using 5 mol % of Ir catalyst, 5 mol % of DIAPHOX 1i, 10 mol % of NaPF6, 10 mol % of LiOAc, and N,O-bis(trimethylsilyl)acetamide (BSA), affording the corresponding branched products in excellent yield and in up to 95% ee. The developed
    描述了使用手性二氨基膦氧化物的Ir催化的不对称烯丙基烷基化。使用5 mol%的Ir催化剂,5 mol%的DIAPHOX 1i,10 mol%的NaPF 6、10 mol%的LiOAc和N,O-双(三甲基甲硅烷基)乙酰胺(BSA)进行末端烯丙基碳酸酯的不对称烯丙基烷基化以极高的收率和高达95%的ee提供相应的分支产品。所开发的催化不对称反应已成功应用于(-)-帕罗西汀的正式对映选择性合成。
  • Iridium-Catalyzed Kinetic Asymmetric Transformations of Racemic Allylic Benzoates
    作者:Levi M. Stanley、Chen Bai、Mitsuhiro Ueda、John F. Hartwig
    DOI:10.1021/ja103779e
    日期:2010.7.7
    Versatile methods for iridium-catalyzed, kinetic asymmetric substitution of racemic, branched allylic esters are reported. These reactions occur with a variety of aliphatic, aryl, and heteroaryl allylic benzoates to form the corresponding allylic substitution products in high yields (74-96%) with good to excellent enantioselectivity (84-98% ee) with a scope that encompasses a range of anionic carbon and heteroatom nucleophiles. These kinetic asymmetric processes occur with distinct stereochemical courses for racemic aliphatic and aromatic allylic benzoates, and the high reactivity of branched allylic benzoates enables enantioselective allylic substitutions that are slow or poorly selective with linear allylic electrophiles.
