Gold and silver: A 1:2 mixture of [(S)‐1}(AuCl)2] and AgBF4 catalyzes the enantioselectivehydroamination of chiral, racemic 1,3‐disubstituted allenes with N‐unsubstituted carbamates to form N‐allylic carbamates in good yield, with high regio‐ and diastereoselectivity, and up to 92 % ee (see scheme, Cbz=benzyloxycarbonyl).
