oxazolo-pyrrolidinones, including a quaternary carbon stereocenter, is described. This was achieved by using a domino process between hydroxy halogenoamides and various Michael acceptors. This strategy provided good to high yield and selectivity. Application to the diastereoselective synthesis of an enantioenriched spirooxindole skeleton in high yield and selectivity is also presented.
描述了对所有碳取代的恶唑并吡咯烷酮(包括季碳立体中心)的有效非对映选择性访问。这是通过使用羟基卤代酰胺和各种迈克尔受体之间的多米诺过程来实现的。该策略提供了良好到高产率和选择性。还介绍了以高产率和选择性非对映选择性合成富含对映体的螺羟吲哚骨架的应用。
