The stereochemical course of the conjugate addition of organocopper reagents, in the presence of TMSCl, is not affected by remote chelation effects, whereas in its absence, the latter may predominate. By this way, it is possible to distinguish, the relative effects of the chelation and of the steric hindrance.
在TMSC1的存在下,共轭添加有机铜试剂的立体化学过程不受远程螯合作用的影响,而在不存在螯合作用的情况下,后者可能占主导地位。通过这种方式,可以区分螯合和位阻的相对作用。
