Correction to Catalytic Enantioselective Protonation of Nitronates Utilizing an Organocatalyst Chiral Only at Sulfur

摘要

We recently established that Scheme 5 in the original manuscript contains incorrect structures. The corrected structures as well as an additional transformation to provide the desired lactams 12 are now provided. a-Carboxy γ-lactams 10 and γ-lactams 11 are now correctly depicted as the N-hydroxy derivatives.
