An organocatalytic asymmetric branching sequence was realized in the presence of 10 mol% of (DHQD)2AQN, affording the sequential products with three stereocentres, including two quaternary carbon centres, in 47%–79% yields with 85%–99% ee.
在10摩尔%(DHQD)2 AQN的存在下实现了有机催化不对称分支序列,提供了具有三个立体中心(包括两个季碳中心)的顺序产物,产率为47%-79%,ee为85%-99%。
