新型手性膦配体的开发一直是有机合成领域的研究重点之一. 本文报道了一种螺旋手性单膦配体的高效合成策略. 基于该方法, 我们成功制备了四种结构新颖的具有螺旋手性的碗状单膦配体, 并系统评估了它们在钯催化的C-C键与C-N键构建反应中作为配体的性能. 通过高效液相色谱(HPLC)拆分, 获得了单一手性的配体. 尽管在上述反应中未能实现理想的对映选择性控制, 但该类配体所展现的独特螺旋手性空腔与优异的配位活性, 表明其在其他不对称催化体系中具有进一步开发与应用的潜力.

The development of novel chiral phosphine ligands is a key area of research in organic synthesis. In this study, we report an efficient synthetic method for the preparation of helically chiral monophosphorus ligands. Using this approach, four structurally distinct, helically chiral, bowl-shaped monophosphorus ligands were successfully synthesized. Their catalytic activities were systematically evaluated in palladium-catalyzed C-C and C-N bond-forming reactions. Enantiopure ligands were obtained via HPLC resolution. Although these reactions did not achieve high enantiocontrol, the ligands demonstrated a unique helical chiral cavity and excellent catalytic activity. These findings suggest that this class of compounds warrants further exploration in other asymmetric catalytic reactions.
