We report herein an efficient NHC-catalyzed kinetic resolution of acyclic tertiary propargylic alcohols that provides them in high to excellent enantioselectivity. This is the first example of kinetic resolution realized by enantioselective acylation. The recovered enantioenriched alcohols can be facilely converted into other valuable compounds such as densely functionalized tertiary alcohols and carbmates
我们在此报道了一种有效的 NHC 催化动力学拆分无环叔炔醇,为它们提供了高至优异的对映选择性。这是通过对映选择性酰化实现动力学拆分的第一个例子。回收的对映体富集醇可以很容易地转化为其他有价值的化合物,例如高产率和优异的立体纯度的密集官能化的叔醇和氨基甲酸酯。进行密度泛函理论计算以确定反应机理并了解对映体歧视的起源。
