                                    Going for gold: The title reaction has been developed and demonstrates a wide substrate scope with respect to the 1,6‐enynes and nitrones (see scheme; DCE=1,2‐dichloroethane, Tf=trifluoromethanesulfonyl). The results for the enantioselective versions are also presented.

金:已经开发了标题反应,展示了关于1,6-
炔烃和硝酮的较宽的底物范围(请参阅方案; DCE = 
1,2-二氯乙烷,Tf =三
氟甲磺酰基)。还给出了对映选择性形式的结果。
