    摘要:
    描述了由由L-缬氨酸制备的手性硫脲催化的β-酮酯向硝基烯烃的高度非对映选择性和对映选择性共轭加成。两个连续的三级和四级立体中心的形成以高收率,极佳的非对映异构和对映异构发生,且催化剂负载量仅为2 mol%。该反应是一般的,并且已经测试了不同的β-酮酯以及芳基-和烷基硝基烯烃。相同的催化剂已被用于促进分子内共轭物的首次加成,从而导致中等非对映选择性和良好对映选择性的环状加合物。

  • Supported and Unsupported Chiral Squaramides as Organocatalysts for Stereoselective Michael Additions: Synthesis of Enantiopure Chromenes and Spirochromanes

    Novel supported chiral bifunctional squaramides have been easily prepared starting from diamines derived from natural amino acids and commercially available aminoalkyl polystyrene resins. These squaramides behave as excellent stereoselective recoverable organocatalysts in different Michael additions, in neat conditions at room temperature.

    motifs in organocatalysis, whereas efficient 1,3‐diamine‐derived organocatalysts are very rare. Herein we report a highly efficient camphor‐1,3‐diamine‐derived squaramide organocatalyst. Its catalytic activity in Michael additions of 1,3‐dicarbonyl nucleophiles to trans‐β‐nitrostyrene derivatives provides excellent enantioselectivities (up to >99% ee).
    手性1,2-二胺是有机催化中的优先结构基序,而高效的1,3-二胺衍生的有机催化剂却很少。在此,我们报告了一种高效的樟脑-1,3-二胺衍生的方酰胺有机催化剂。它在1,3-二羰基亲核试剂与反式-β-硝基苯乙烯衍生物的迈克尔加成反应中的催化活性提供了出色的对映选择性(高达ee大于99%)。

    Three novel fullerothioureas derived from natural valine, phenylalanine, and tert-leucine have been prepared by Prato's reaction of [60]fullerene and the corresponding aldehydes. These hybrids have been used as organocatalysts in a typical stereoselective nitro-Michael addition reaction under homogeneous and neat conditions. The catalysts are easily recoverable by filtration, and are recyclable for

  • A Recyclable Hydrophobic Anchor-Tagged Asymmetric Amino Thiourea Catalyst
    作者:Takahisa Jichu、Tsubasa Inokuma、Keisuke Aihara、Taiki Kohiki、Kodai Nishida、Akira Shigenaga、Ken-ichi Yamada、Akira Otaka
    DOI:10.1002/cctc.201800714
    日期:2018.8.21
    A novel, recyclable, thiourea‐based asymmetric organocatalyst containing a hydrophobic anchor has been developed. The chemical nature of the hydrophobic anchor contributes to the desirable characteristics of the recyclable catalyst. The hydrophobic anchor‐tagged thiourea catalyst is highly soluble in less polar solvents, which is compatible with amino thiourea catalyst‐mediated asymmetric reaction
    已经开发了一种新型的,可回收的,基于硫脲的不对称有机催化剂,其中含有疏水性锚。疏水性锚的化学性质有助于可回收催化剂的所需特性。疏水性锚固标记的硫脲催化剂在极性较小的溶剂中高度可溶,与氨基硫脲催化剂介导的不对称反应条件相容,但在再循环过程中仅少量溶于极性溶剂。这种不对称催化剂提供的催化性能可与母体催化剂媲美,并且可以很容易地从反应中回收利用。
