The old switcheroo: The switch in the enantioselectivity of a reaction by using a single chiral source has been achieved using different metal binding modes of the chiral amino alcohol 1 in the presence of CuI and AgI sources. Azomethine ylides were shown to undergo highly enantio‐ and diastereoselective 1,3‐dipolar cycloadditions with substituted tert‐butyl acrylates to provide both of the enantiomerically
旧的switcheroo:在存在Cu I和Ag I源的情况下,通过使用手性
氨基醇1的不同
金属键合模式,已经实现了使用单一手性源进行反应对映选择性的转换。已显示,甲亚甲酰
