The assembly of a wide range of dialkylzincs, cyclic enones, and chiral N-tert-butylsulfinyl imines in the presence of the appropriate phosphoramidite ligands allowed the formation of β-amino ketones with three consecutive stereogenic centers in a stereocontrolled manner. The Baeyer−Villiger oxidation of the resulting amino ketones led to the corresponding aminolactones with excellent regio- and stereoselectivities
该组件广泛二烷基锌,环烯酮,和手性的ñ -叔丁基亚亚胺在合适的亚磷酰胺配位体的存在下允许β氨基酮的形成在一个立体控制的方式连续三个手性中心。所得氨基酮的拜耳-维利格氧化导致相应的氨基内酯具有良好的区域选择性和立体选择性。
