摘要：
Two of a kind: A new type of counterion-mediated syn-addition mechanism has been presented in gold-catalyzed enantioselective hydroamination reactions with [(R)-binap(AuOPNB)2] (OPNB=para-nitrobenzoate). A combination of both hydrogen bonding and the N-Au interaction efficiently controlled the challenging enantioselectivity of allenes. © 2011 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
