手性铜催化剂催化的不对称分子内环丙烷化反应
Asymmetric Intramolecular Cyclopropanation Using a Chiral (β-Diketone)-Copper Complex as a Catalyst
【摘要】 以手性 β 二酮 -铜配合物Cu(dcm) 2 为催化剂 ,研究了重氮乙酸烯醇酯的分子内不对称环丙烷化反应 ,获得较高光学产率的环化产物 ,同时提出了不对称催化可能的反应机理和手性识别模型
【Abstract】 Asymmetric intramolecular cyclopropanation of allylic diazoacetate was investigated using a chiral (β-diketone)-copper complex as an efficient catalyst and high optical yield was achieved. A possible reaction mechanism was proposed to explain the observed stereoselectivity.
