Abstract
Two new diastereomeric dihydroisoquinoline-derived iminium salts containing an asymmetric center in the exocyclic substituent at the nitrogen atom were prepared and tested as catalysts for the enantioselective epoxidation of prochiral di- and trisubstituted alkenes. Enhanced catalytic efficiency against a reference N-methyliminium salt was observed.
