Abstractmagnified imageThe first direct approach for the asymmetric synthesis of (E)‐2‐arylidene‐1,4‐diphenylbut‐3‐yn‐1‐amines by addition of alkynylzinc to chiral N‐tert‐butylsulfinylimines is reported with excellent diastereoselectivity and good yield. This asymmetric addition reaction provides a practical, economical and concise synthesis of multifunctional molecules with the 1,3‐enyne side chain and an amino group. In addition, this methodology can be applied to the synthesis of substituted vinyl iodide compounds, and substituted chiral dihydropyrroles.
