GRAPHICAL ABSTRACT ABSTRACT A Lewis acid-catalyzed asymmetric addition reaction of β-methyl- or γ-methyl-substituted acyclic silyl dienolates 2 with α-fluoroalkylsulfinylimines 1 furnished complex fluorinated aminoesters in high yield under stereocontrol. Two different transition states were proposed to explain the observed selectivity.
