    锂化动力学拆分:取代的二氢苯并恶嗪和四氢喹喔啉的高度对映选择性合成
    摘要:
    动力学拆分提供了一种高度对映选择性的方法,可以使用正丁基锂和手性配体 sparteine 获取一系列 3-芳基-3,4-二氢-2H-1,4-苯并恶嗪。在去除叔丁氧基羰基 (Boc) 保护基团时,对映体富集仍然很高。中间体有机锂开环生成烯胺。动力学分辨率扩展到对映体富集的取代 1,2,3,4-四氢喹喔啉,并应用于抗生素左氧氟沙星的类似物的合成,该类似物已筛选其对人类病原体肺炎链球菌的活性。

  • Highly Enantioselective SPINOL-Derived Phosphoric Acid Catalyzed Transfer Hydrogenation of Diverse C=N-Containing Heterocycles
    作者:Yiliang Zhang、Rong Zhao、Robert Li-Yuan Bao、Lei Shi
    DOI:10.1002/ejoc.201500330
    日期:2015.5
    A highly efficient and enantioselective hydrogenation of diversely substituted C=N-containing heterocyclic compounds such as 3-aryl-1,4-benzoxazines and 2-arylquinolines was experimentally explored by using 1,1′-spirobiindane-7,7′-diol-derived chiral phosphoric acids as the catalyst. This method provides straightforward access to the corresponding tetrahydroquinolines and dihydro-2H-1,4-benzothiazines
    通过使用 1,1'-spirobiindane-7,7'-diol- 实验探索了多种取代的 C=N 杂环化合物(如 3-芳基-1,4-苯并恶嗪和 2-芳基喹啉)的高效和对映选择性氢化反应。衍生手性磷酸作为催化剂。该方法可以直接获得相应的四氢喹啉和二氢-2H-1,4-苯并噻嗪,收率高(85-99%),具有出色的对映选择性(91-99%)。该方法的吸引人的特点包括反应条件温和、操作简单、催化剂负载量相对较低 (1 mol-%) 和高水平的对映选择性,使其成为实际合成光学活性含氮芳香杂环的有用方法.

    A transition-metal-free method for the B(C6F5)3-promoted hydrogenations of N-heterocycles using ammonia borane under mild reaction conditions has been developed. The reaction affords a broad range of hydrogenated products in moderate to good yields. The enantioselective versions for the corresponding products were also investigated via our approach, showing good feasibility.

    Two homochiral organocatalytic MOMs were prepared using tetra- and octa-carboxylate ligands, respectively. The nanoscopic channels in these MOMs are lined by organonocatalytic chiral phosphoric acid derivatives of binol and ocMOM-1 exhibited improved enantioselectivity over the parent ligand in the context of transfer hydrogenation of a series of benzoxazines.
    利用四羧酸配体和八羧酸配体分别制备了两种同手性有机催化 MOM。在一系列苯并噁嗪的转移加氢反应中,ocMOM-1 比母体配体表现出更高的对映选择性。
  • Asymmetric Transfer Hydrogenation of Heterocyclic Compounds in Continuous Flow Using an Immobilized Chiral Phosphoric Acid as the Catalyst
    作者:Pavel Nagorny、Oleksii Zhelavskyi、Yin-Jia Jhang
    DOI:10.1055/a-2085-5256
    日期:2023.8
    This manuscript describes transfer hydrogenation of bicyclic nitrogen-containing heterocyclic compounds using the immobilized chiral phosphoric acid catalyst (R)-PS-AdTRIP in batch and continuous flow. A significant improvement in enantioselectivities is achieved in continuous flow with a fluidized bed reactor packed with (R)-PS-AdTRIP when the flow rate is increased from 0.2 mL/min to 2.0–2.5 mL/min
    该手稿描述了使用固定化手性磷酸催化剂 ( R )-PS-AdTRIP 以间歇和连续流进行双环含氮杂环化合物的转移氢化。当流速从 0.2 mL/min 增加到 2.0–2.5 mL/min 时,使用填充 ( R )-PS-AdTRIP的流化床反应器在连续流动中实现了对映选择性的显着改善。优化的连续流动条件始终比使用 2 mol% ( R )-PS-AdTRIP 的间歇转移氢化提供高 4–6% ee 的选择性,并用于使用相同的流化床反应器生成多种手性产物。
  • An Organocatalyst Bearing Stereogenic Carbon and Sulfur Centers as an Efficient Promoter for Enantioselective Hydrosilylation of 1,4-Benzooxazines
    作者:Xiang-Wei Liu、Chao Wang、Yan Yan、Yong-Qiang Wang、Jian Sun
    DOI:10.1021/jo400187e
    日期:2013.6.21
    The efficient and enantioselective hydrosilylation of 3-aryl-1,4-benzooxazines was achieved using an l-phenyl alanine derived new Lewis base catalyst bearing stereogenic carbon and sulfur centers. In the presence of 2 mol % of catalyst, a broad range of 3-aryl-1,4-benzooxazines were hydrosilylated to afford the corresponding chiral 3-aryl-3,4-dihydro-2H-1,4-benzooxazine products with good to high yields (66-98%) and enantioselectivities (70-99% ee). This method provides an alternative approach with great practical application potential to access chiral 3-aryl-3,4-dihydro-2H-1,4-benzooxazines.
