A gold(I)‐catalyzed highly diastereo‐ and enantioselective intermolecular cycloaddition of oxime ethers with nitrones under mild conditions was developed, which provides an facile access to optically pure highly substituted pyrrolo[3,4‐d][1,2]oxazines. The salient features of this reaction include general substrate scope, high efficiency, high enantioselectivity, readily available starting materials
在温和条件下,金(I)催化了肟醚与硝酮的高度非对映异构和对映选择性分子间环加成反应,从而可以轻松获得光学纯的高度取代的吡咯并[3,4- d ] [1,2]恶嗪。该反应的显着特征包括一般的底物范围,高效率,高对映选择性,易于获得的起始原料以及可商购的配体的使用。
