On May 20, 2022, Gaertner, Cornelius V.; Schneider, Christoph published an article.Reference of Methyl 2-cyclopentanonecarboxylate The title of the article was Enantioselective Annulation of α,β-Unsaturated N-Acyliminium Ions with β-Keto Ester Enolates via Cooperative Palladium and Bronsted Acid Catalysis. And the article contained the following:
Authors herein report a cooperative palladium- and Bronsted acid-catalyzed strategy toward the first enantioselective annulation of in situ generated α,β-unsaturated N-acyliminium ions with chiral metal enolates. Novel polycyclic oxoisoindoles featuring three contiguous stereogenic centers have been obtained with typically good yields, outstanding enantiocontrol, and moderate to good diastereoselectivity. The utility of the process was further demonstrated by their conversion to synthetically valuable scaffolds. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Reference of Methyl 2-cyclopentanonecarboxylate
