Pin the amine on the gamma: A new method has been developed for the γ-addition of nitrogen nucleophiles to γ-substituted alkynoates or allenoates through intra- and intermolecular processes that are catalyzed by spirophosphine 1 (see scheme). An asymmetric version of this reaction affords enantioenriched pyrrolidines, indolines, and γ-amino-α,β- unsaturated carbonyl compounds.
