  • A <scp>d</scp> -Camphor-Based Schiff Base as a Highly Efficient N,P Ligand for Enantioselective Palladium-Catalyzed Allylic Substitutions
    作者:Qiao-Ling Liu、Weifeng Chen、Qun-Ying Jiang、Xing-Feng Bai、Zhifang Li、Zheng Xu、Li-Wen Xu

    New Schiff bases derived from chiral d‐camphor were determined to be effective phosphine ligands for the asymmetric palladium‐catalyzed allylic alkylation of activated methylene compounds, the allylic etherification of alcohols, and the allylic amination of primary amines or secondary amines, in which the corresponding products with various functional groups were achieved in good yields with excellent
    从手性衍生的新的席夫碱d -樟脑被确定为用于活化的亚甲基化合物的不对称钯催化的烯丙基烷基化,醇的烯丙基醚化,和伯胺或仲胺的烯丙基胺化,其中,对应的有效的膦配体具有良好收率和优异的对映选择性(高达> 99%ee),可以得到具有各种官能团的产物 。值得注意的是,衍生自席夫碱L2的钯催化剂提供了迄今为止报道的最高水平的对映选择性,可用于烯丙基取代反应,包括烯丙基醚化和烯丙基胺化反应,从而揭示了d的特殊作用。钯催化的烯丙基取代反应中源自樟脑的席夫碱。
  • C–N Bond Cleavage of Allylic Amines via Hydrogen Bond Activation with Alcohol Solvents in Pd-Catalyzed Allylic Alkylation of Carbonyl Compounds

    Hydrogen-bond-activated C-N bond cleavage of allylic amines was realized in Pd-catalyzed allylic alkylation to form the C-C bond product. The method could be expanded to a series of allylic amines and carbonyl compounds with excellent results. It provides a new and convenient access to C-C bond formation based on Pd-catalyzed allylic alkylation of allylic amines by using only inexpensive alcohol solvents.
    烯丙胺的氢键活化 CN 键断裂是在 Pd 催化的烯丙基烷基化中实现的,以形成 CC 键产物。该方法可以扩展到一系列烯丙基胺和羰基化合物,并取得了优异的结果。它通过仅使用廉价的醇溶剂,为基于 Pd 催化的烯丙基胺的烯丙基烷基化形成 CC 键提供了一种新的便捷途径。

    atropselectively—because of point‐to‐axial asymmetric inductions—and atropdivergently, exhibiting up to 95 % (M)‐ and as much (P)‐atropselectivity. This route to atropisomerically pure biaryls is novel and should extend to other substrates and/or different functionalizations. The dibromobiindolyls (M)‐ and (P)‐18 a furnished the biindolyldiphosphanes (M)‐ and (P)‐14 without atropisomerization. These syntheses did
