经历钯-卡宾中间体的不对称环化反应为构建手性环状骨架提供了高效途径, 但其发展仍面临重大挑战. 本研究报道了一种钯催化的不对称[4+1]环化反应, 利用动态多配体接力不对称催化策略, 成功构建手性茚满类化合物. 该配体接力体系采用双齿Pyrox配体促进氧化加成步骤, 同时使用单齿Feringa型磷酰胺配体促进卡宾化/迁移插入过程及后续分子内Tsuji-Trost反应.

Asymmetric annulation via palladium-carbene intermediates offers a powerful route to chiral cyclic frameworks, yet its development remains a significant challenge. Here, a Pd-catalyzed asymmetric [4+1] annulation for constructing chiral indanes is disclosed, enabled by a novel dynamic multiligand relay asymmetric catalysis. The ligand relay system employs a bidentate Pyrox ligand to promote the oxidative addition, while a monodentate Feringa-type phosphoramidite ligand facilitates the carbenation/migratory insertion step and the following intramolecular Tsuji-Trost reaction. The practical utility of this method was confirmed through a scale-up experiment. This strategy establishes a practical and efficient route to enantioenriched vicinal substituted indanes.
