Some of the Lewis acid catalyzed Michael additions to a,3-unsaturated carbonyls can also be rationalized based on these models. For example, BFs-mediated additions of organocopper reagents to chiral a,3-unsaturated esters such as (-)-8-phenylmenthyl crotonate (35) occur with high levels of dia-stereoselectivity. " The product stereochemistries for these reactions could be predicted by assuming the reactive conformation (35S), which follows the basic structural tenets of model A (Figure 41). ...
