It all adds up! A modified Feist–Bénary reaction employing a dominoMichael–alkylation sequence was designed for the enantioselective synthesis of 3(2 H)‐furanones. L‐Threonine‐derived tertiary amine/thiourea catalysts were prepared for the first time; such catalysts promoted the designed dominoMichael–alkylationreactions in a highly enantioselective manner (see scheme).
