Enantioselective α‐Aminoxylation of Ketones Catalyzed by a Chiral Brønsted Acid

Development of new asymmetric radical reactions is of significant interest to the synthetic community. In this article, we describe a chiral Brønsted acid catalyzed enantioselective α‐oxidation of ketones carrying heteroaromatic templates using TEMPO and a metal oxidant. The methodology provides access to α‐aminoxylated ketones in high yields and good enantioselectivities.
