Enantioselective Addition of Pyrazoles to Dienes** [PDF]

Angewandte Chemie International Edition, 2021
Abstract We report the first enantioselective addition of pyrazoles to 1,3‐dienes. Secondary and tertiary allylic pyrazoles can be generated with excellent regioselectivity. Mechanistic studies support a pathway distinct from previous hydroaminations: a Pd 0 ‐catalyzed ...
