[摘要]:Ag(I)-catalyzed intramolecular reaction of monoarylmethylenecyclopropanes (MCPs) tethered with 1,1,3-triarylprop-2-yn-1-ols provides diastereoselective access to polysubstituted allenylcyclobutanols and the obtained allenylcyclobutanols catalyzed by Au(I) furnish a wide range of bridged bicyclic compounds with a vinyl-substituted quaternary stereogenic center stereo selectively. |
