A method providing expeditious access to chiral allylic amines via a Rh(I)/bicyclo[2.2.1]heptadiene‐catalyzed enantioselective alkenylation of N‐tosyl aldimines with potassium alkenyltrifluoroborates under microwave irradiation is described. The rate of the asymmetric 1,2‐addition reaction, conducted in the presence of 1 mol % of the catalyst, was significantly enhanced as compared to when the standard
