Water‐Catalytic Deconstructive and Proton Transfer Cyclopropanation of Sulfoxonium Ylide with Olefin

Advanced Science, EarlyView.
Water‐catalytic deconstructive and proton transfer cyclopropanation of sulfoxonium ylide with olefin is developed through a sequential water‐mediated ring‐closing/opening reaction. This atom‐economical, environmentally friendly methodology offers easy access to a range of cyclopropyl ketones with moderate to good yields.
