Coppertunity knocks: An inexpensive, practical, and environmentally benign procedure for the enantioselective addition of glycine derivatives to α,β‐unsaturated ketones has been developed (see scheme). By modifying the workup, the conjugate addition product or a cyclic imine can be accessed. The solution structure of the catalyst–substrate complex is shown to be key to the overall reaction selectivity
铜tun敲击:已开发出一种廉价,实用且对环境有益的方法,用于将甘氨酸衍生物对映选择性地添加到α,β-不饱和酮中(参见方案)。通过修改后处理,可以得到缀合物加成产物或环状亚胺。催化剂-底物配合物的溶液结构显示出对整体反应选择性的关键。
