Bridging a gap: A cationic rhodium(I)/ligand complex catalyzes the title reaction of alkynes and amide‐linked 1,5‐dienes, leading to bridged multicyclic compounds, with high chemo‐, regio‐, and enantioselectivity (see scheme; Bn=benzyl).
缩小差距:阳离子铑(I)/配体络合物催化炔烃和酰胺键合的1,5二烯的标题反应,导致桥联的多环化合物具有较高的化学,区域和对映选择性(见方案; Bn =苄基)。
