The recent booming of gold catalysis has demonstrated that unprecedented transformations can be realized in a highly selective manner. Moreover, due to the growing availability of chiral organic ligands, gold-catalysis can be considered as one of mos

A 1:2 mixture of [(S)-2](AuCl)2 [(S)-2 = (S)-3,5-t-Bu-4-MeO-MeOBIPHEP] and AgBF4 catalyzes the stereoconvergent, intermolecular enantioselective hydroamination of chiral, racemic 1,3-disubstituted allenes with N-unsubstituted carbamates to form N-all
