title: Rhodium(I)-catalyzed cycloisomerization of 1,6-enynes to bicyclo[4.1.0]heptenes.
abstract: Efficient rhodium(I)-catalyzed cyclopropanation reactions of nitrogen-tethered 1,6-enynes to azabicyclo[4.1.0]heptenes are reported. Moreover, rhodium(I)-catalyzed tandem cycloisomerization and carbonylative [3+3+1] cycloaddition reactions of a cyclopropylenyne have been observed.
