This work reports the first efficient enantioselective intramolecular Buchner reaction of diazoacetamides. The Ru(II)–Pheox catalyst was shown to be highly efficient in this transformation in terms of both the regio- and enantioselectivity (up to 99% ee) giving the desired products in quantitative yield.
这项工作报告了重氮乙酰胺的第一个有效的对映选择性分子内布赫纳反应。在区域转化和对映选择性(高达99%ee)方面,Ru(II)-Pheox催化剂在这种转化中均表现出很高的效率,从而可以定量获得所需的产物。
