The stereochemical course of the conjugate addition of organocopperreagents, 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.
