  为 Morita-Baylis-Hillman 反应设计一种高效的对映选择性酶

  摘要：

  计算设计和定向进化的结合可以提供一种通用策略来创建具有新功能的酶。到目前为止，这种方法已经为少数模型反应提供了酶。在这里，我们表明可以将新的催化机制设计到蛋白质中以加速更具挑战性的化学转化。原始设计的进化优化为 Morita-Baylis-Hillman (MBH) 反应提供了一种高效的对映选择性酶 (BH32.14)。BH32.14 适用于制备规模的转化，接受范围广泛的醛和烯酮偶联伙伴，并能够促进二醛的选择性单官能化。晶体学、生物化学和计算研究表明 BH32。14 通过复杂的催化机制运作，该机制包括 His23 亲核试剂与明智定位的 Arg124 配对。这种催化精氨酸在构象状态之间穿梭以稳定多个氧阴离子中间体，并作为特殊双齿氢键催化剂（例如，硫脲）的遗传编码替代物。这项研究表明，可以从头开始构建精心设计的催化装置，以促进在自然界中未观察到的要求苛刻的多步过程。

  Palladium complexes with an axially chiral N–Ar framework have been developed. These complexes showed high stereoselectivities in asymmetric allylic arylation to achieve the kinetic resolution of Morita–Baylis–Hillman adducts, affording up to 99% ee of (E)-allylation products and 92% ee of recovered Morita–Baylis–Hillman adducts.

  我们开发了具有轴向手性 NâAr 框架的钯配合物。这些配合物在不对称烯丙基芳基化过程中表现出很高的立体选择性，从而实现了莫里塔-贝利斯-希尔曼加合物的动力学解析，得到的(E)-烯丙基化产物的ee高达99%，回收的莫里塔-贝利斯-希尔曼加合物的ee高达92%。
• Cationic chiral surfactant based micelle-guided asymmetric Morita-Baylis-Hillman reaction

  Cationic chiral surfactant (1R, 2S)-(-)-N-dodecyl-N-methylephedrinium bromide (DMEB) was utilized for the first time in inducing asymmetry to Morita-Baylis-Hillman reaction in aqueous medium. Proton NMR studies carried out to determine the locus of the reaction in micro-heterogeneous micellar environment, were found useful in proposing a plausible model for asymmetric induction. This work demonstrates that under such mild and nonhazardous reactions conditions, the reaction rates increase, good yields are favored and above all reasonable enantiomeric excesses are obtained.

• Asymmetric Morita-Baylis-Hillman Reaction of Arylaldehydes with 2-Cyclohexen-1-one Catalyzed by Chiral Bis(Thio)urea and DABCO

  Novel bis(thio)urea organocatalysts were synthesized from axially chiral (R)-(-)-5,5',6,6',7,7',8,8'-octahydro-1,1'-binaphthyl-2,2'-diamine (H-8-BINAM), and their catalytic abilities have been examined in the Morita-Baylis-Hillman reaction of 2-cyclohexen-1-one or 2-cyclopenten-1-one with a wide range of aromatic aldehydes in combination with DABCO. The best result was achieved in the reaction of 3-fluorobenzaldehyde with 2-cyclohexen-1-one to give the desired Morita-Baylis-Hillman product in 79% yield and 88% ee.
