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%... 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. 展开更多
