prepared via this method can be directly used in the frequently employed Cadiot–Chodkiewicz coupling to produce functionalized diynes. The method reported here increases the structural diversity of chiral terminal bromo-substituted propargylamines that can be readily synthesized as previous methods for the stereoselective synthesis of these compounds rely on aminoacid precursors from the chiral pool.

stereoselective addition of lithiated chloroacetylene, derived in situ from cis-1,2-dichloroethene and methyl lithium, to Ellman chiral N-tert-butanesulfinyl imines is reported. The reaction proceeds in high yield (up to 98%) and with excellent diastereoselectivity (up to >20:1) for a variety of aryl, heteroaromatic, alkyl, and α,β-unsaturated imine substrates. Transformations of the terminal chloro-substituted
