The asymmetric allylic alkylation reaction of sulfonylimidates with various Morita-Baylis-Hillman (MBH) carbonates was accomplished by the catalysis of commercially available cinchonaalkaloids catalyst (DHQD)2AQN. The corresponding allylic alkylation products were obtained in good yields with high stereoselectivities (up to 99% ee, 89:11 dr).
