  The enantioselective 1,6-addition to unsaturated carbonyl compounds offers unique opportunities to study the range of selectivities one can obtain using Cu catalysis. Here, a substrate–reagent approach to obtain structural information on the mechanism of extended conjugate additions is reported. By studying the influence of several halides in the Grignard reagent and in the Cu source on the enantioselective

  对不饱和羰基化合物的1,6-对映选择性加成提供了独特的机会来研究使用Cu催化可获得的选择性范围。在这里，报道了一种底物-试剂方法来获得有关扩展缀合物加成机理的结构信息。通过研究格氏试剂和铜源中几种卤化物对对映选择性1,6-加成的影响，表明使用EtMgBr作为格氏试剂和CuI作为铜源的组合是有利的。此外，探索带有几种烷基酯的底物发现，叔丁基酯底物增强了1,6-加成中的对映异构，并允许添加BnCH 2溴化镁。还研究了具有各种吸电子基团的底物，确定酯底物最适合1,6加成。其他两项研究的重点是Me取代的烯烃底物和具有所有可能的烯烃几何形状的底物。这些研究表明，当使用α-Me底物时，在1,6-加成中空前的高对映选择性，并为1,6-加成机理提供了相关见解。最后，研究了具有三个或四个烯烃与吸电子基团共轭的底物。在此，报道了1，8-加成，其以合理的产率，区域选择性和立体选择性给出了相应的产物。结合这些研究
