mixture of [(S)-1]Au2Cl2 [(S)-1 = (S)-3,5-t-Bu-4-MeO-MeOBIPHEP] and AgClO4 in m-xylene at -40 degrees C for 24 h led to isolation of 2-vinylpyrrolidine 3a in 97% yield with 81% ee. Gold(I)-catalyzed enantioselective hydroamination was effective for a number of carbamate groups and tolerated terminal disubstitutution of the allenyl moiety.
用[(S)-1] Au2Cl2 [(S)-1 =(S)-3,5-t-Bu-4-MeO)1:2催化混合物处理N-4,5-己二烯基氨基甲酸酯2a [-MeOBIPHEP]和AgClO4在-40°C的间二甲苯中放置24小时,从而以97%的收率分离出2-乙烯基吡咯烷3a,ee值为81%。金(I)催化的对映选择性氢化胺化对于许多氨基甲酸酯基团和可承受的烯基部分的末端去位取代作用是有效的。
