Pd/Cu-catalyzed cascade Heck-type reactions of alkenyl halides with terminal alkynes toward substituted pyrrolidine analogues

Pd/Cu-catalyzed cascade Heck-type reactions of alkenyl halides with terminal alkynes have been developed. This research provides an efficient atom-economical approach to access a variety of highly substituted pyrrolidines in moderate to good yields. This protocol features readily available substrates, broad substrate scope, easy scale-up, high selectivities and versatile transformations.
