  Stereoselective Synthesis of Norephedrine and Norpseudoephedrine by Using Asymmetric Transfer Hydrogenation Accompanied by Dynamic Kinetic Resolution

  摘要：

  Each of the enantiomers of both norephedrine and norpseudoephedrine were stereoselectively prepared from the common, prochiral cyclic sulfamidate imine of racemic 1-hydroxy-1-phenyl-propan-2-one by employing asymmetric transfer hydrogenation (ATH) catalyzed by the well-defined chiral Rh-complexes, (S,S)- or (R,R)-Cp*RhCl(TsDPEN), and HCO2H/Et3N as the hydrogen source. The ATH processes are carried out under mild conditions (rt, 15 min) and are accompanied by dynamic kinetic resolution.

  bromodomain‐containing lysine acetyl transferases are members of subfamily I of the bromodomain phylogenetic tree. Iterative cycles of rational inhibitor design and biophysical characterization led to the discovery of the triazolopthalazine‐based L‐45 (dubbed L‐Moses) as the first potent, selective, and cell‐active PCAF bromodomain (Brd) inhibitor. Synthesis from readily available (1R,2S)‐(−)‐norephedrine furnished

  p300 / CBP相关因子（PCAF）和相关的GCN5含溴结构域的赖氨酸乙酰基转移酶是溴结构域系统发育树的亚家族I的成员。合理的抑制剂设计和生物物理特征的反复循环导致发现了基于三唑并噻嗪的L-45（称为L-Moses）作为第一种有效的，选择性的和具有细胞活性的PCAF溴结构域（Brd）抑制剂。由易于获得的（1R，2S）-（-）-去氧麻黄碱合成的对映纯形式的L-45。L-45显示出扰乱使用nanoBRET测定细胞PCAF-BRD组蛋白H3.3相互作用，和的共晶体结构L-45与来自恶性疟原虫的同源Brd PfGCN5的组合合理化了对PCAF和GCN5溴结构域的高选择性。化合物L-45在外周血单核细胞（PBMC）中没有可观察到的细胞毒性，在人和小鼠肝微粒体中没有良好的细胞渗透性和代谢稳定性，支持其在体内使用的潜力。

  Protic aminophosphines with multiple chiral centers were synthesized in good yields and high purity by the nucleophilic ring-opening of N-protected cyclic sulfamidates with metal phosphides, followed by hydrolysis and deprotection. This synthetic approach is clean, scalable, and high yielding. The method provides an efficient alternative route for the synthesis of chiral aminophosphines.

  The present application is directed to i) a method for synthesizing aminophosphine (P,N) and phosphine-aminophosphine (P,N,P) ligands, ii) the use of such ligands in the preparation of metal complexes as hydrogenation catalysts, and iii) aminophosphine (P,N) and phosphine-aminophosphine (P,N,P) ligands of various structures. In particular, the methods in i) involve reacting a protected tertiary amine of formula (I) with a metal phosphide of the formula Y—PR8R9 to afford an aminophosphine of formula (II), which can then be optionally further reacted with a phosphine of the formula (III) to afford the phosphine-aminophosphine of formula (IV).
