Although the organocatalytic direct asymmetricMichaelreactions of carbonyl compounds to nitroalkenes have been investigated intensely, the Michaelreaction of the thioether‐based donors remains a rather undeveloped field. This work concerns the asymmetricMichael addition of aryl sulfanyl‐propan‐2‐one to nitroalkenes with benzoic acid as an additive, and chiral amine‐thiourea as a bifunctional organocatalyst
