Abstract
A synthetic approach for the construction of functionalized diverse 1-pyrrolines incorporating β-quaternary carbon centers under mild reaction conditions has been reported, in which α-allyl α-(alkylideneamino)nitriles generated from a Lewis base-catalyzed allylic alkylation reaction engaged in a Lewis base-mediated tandem intramolecular cyclization to deliver the targeted molecules in a catalytically atom-economic fashion.
