A de novo intramolecular hydroamination of conjugated enynes was developed using commercially available n-BuLi as a precatalyst. This hydroamination reaction successfully afforded allenyl-substituted pyrrolidines with up to 95% yield. One of the resulting allenyl pyrrolidines was converted to the natural products irniine and irnidine in three steps.

intramolecular hydroamination of conjugatedenyne was developed using commercially available n-BuLi as a precatalyst. This hydroamination reaction led to products with allene and pyrrolidine functional groups. One of the enyne hydroamination products was successfully converted to natural products irniine and irnidine in three steps. The scope and mechanism of the enyne hydroamination are also discussed
