title: Highly Selective Ring Expansion of Bicyclo[3.1.0]hexenes.
abstract: A Ru-carbene-promoted ring expansion of bicyclo[3.1.0]hexenes with terminal alkynes is reported. The reaction delivers seven-membered carbocycles starting from readily available starting materials and was found to be highly regioselective. The resulting seven-membered ring products contain both conjugated diene and cyclopropane substructures that could be selectively reacted in subsequent transformations.
