| Abstract: | The first enantioselective aminolysis of aromatic trans‐2,3‐epoxy sulfonamides has been accomplished, which was efficiently catalyzed by a Gd‐N,N′‐dioxide complex. Under the directing effect of the sulfonamide moiety the ring‐opening reaction proceeded selectively at the C‐3 position in a highly enantioselective manner furnishing various Ts‐ and SES‐protected 3‐amino‐3‐phenylpropan‐2‐olamines as products. |
