Abstract
![]()
Herein, we describe
an efficient nanocopper-catalyzed Alder-ene
reaction of allenynamides. The copper nanoparticles were immobilized
on amino-functionalized microcrystalline cellulose. A solvent-controlled
chemoselectivity of the reaction was observed, leading to the chemodivergent
synthesis of pyrrolines (2,5-dihydropyrroles) and pyrroles. The heterogeneous
copper catalyst exhibits high efficiency and good recyclability in
the Alder-ene reaction, constituting a highly attractive catalytic
system from an economical and environmental point of view.

Abstract
The generation of metal carbenes from readily available alkynes represents a significant advance in metal carbene chemistry. However, most of these transformations are based on the use of noble-metal catalysts and successful examples of such an asymmetric version are still very scarce. Here a copper-catalyzed enantioselective cascade cyclization of N-propargyl ynamides is reported, enabling the practical and atom-economical construction of diverse chiral polycyclic pyrroles in generally good to excellent yields with wide substrate scope and excellent enantioselectivities (up to 97:3 e.r.). Importantly, this protocol represents the first copper-catalyzed asymmetric diyne cyclization. Moreover, mechanistic studies revealed that the generation of donor/donor copper carbenes is presumably involved in this 1,5-diyne cyclization, which is distinctively different from the related gold catalysis, and thus it constitutes a novel way for the generation of donor/donor metal carbenes.
