Significance

Enantioselective hydrogenation of pyrroles would provide direct access to chiral ­pyrrolidine rings. The current work succeeded in ­using 2,3,5-trisubstituted pyrroles as substrate to give all-cis pyrrolidine products with three chiral centers, or chiral 4,5-dihydropyrroles. Basically, this method is a powerful entry to chiral pyrrolidine, very useful for pharmaceutical applications as well as organocatalysis.
