Asymmetric recognition and sequential ring opening of 2-substituted-N-nosylaziridines with (DHQD)(2)AQN and TMSNu

A new method for asymmetric ring opening of terminal aziridines using a chiral amine, (DHQD)(2)AQN, is described; the reaction is based on the asymmetric recognition of aziridines using (DHQD)(2)AQN and on sequential ring opening using TMSNu.
