Rhodium(I)-Catalyzed Vinylation/[2+1] Carbocyclization of 1,6-Enynes with alpha-Diazocarbonyl Compounds

A sequential Rh(I)-catalyzed vinylation/[2 + 1]carbocyclization between enynes and diazo compounds has been developed. This transformation features a wide range of enynes and acceptor/acceptor diazo compounds, providing easy access to versatile vinyl-substituted azabicyclo[3.1.0]hexanes having a broad tolerance to functional groups.
