Enanatiopure β‐methyl‐γ‐monofluoromethyl alcohols were prepared from the allylic alkylation between fluorobis(phenylsulfonyl)methane with Morita–Baylis–Hillmancarbonates. The reaction was catalyzed by using the Cinchonaalkaloid derivative, (DHQD)2AQN. The origin of the stereoselectivity was verified by DFT methods. Calculated geometries and relative energies of various transition states strongly
