轴手性膦化合物在不对称催化中具有重要价值, 但其高效合成仍面临显著挑战. 本研究通过氮杂环卡宾(NHC)催化双醛与芳基硼酸的酯化反应, 成功构建了轴手性磷化合物骨架. 机理研究表明, 该反应首先经历去对称化过程, 随后通过动力学拆分途径, 最终以高对映选择性(最高达92% ee)获得了一系列的轴手性磷化合物.

关键词: 轴手性磷化合物, 氮杂环卡宾, 酯化, 去对称化

Atropisomeric phosphines are crucial for asymmetric catalysis but remain synthetically challenging. Herein, an N-heterocyclic carbene (NHC) catalyzed esterification reaction of dialdehydes with arylboronic acids was developed, successfully constructing the framework of axially chiral phosphorus compounds. Mechanistic studies have revealed that the reaction initially undergoes a desymmetrization process, followed by a kinetic resolution pathway, affording a series of axially chiral phosphorus compounds with high enantioselectivity (up to 92% ee).

Key words: axially chiral phosphorus compounds, N-heterocyclic carbene, esterification, desymmetrization
