Cyclopropyl radical clock alcohol
WebA Rh(III)-catalyzed diastereoselective [2+1] annulation of allylic alcohols with N-enoxyphthalimides provides substituted cyclopropyl-ketones. Notably, the traceless oxyphthalimide handle serves three functions: directing C-H activation, oxidation of Rh(III), and controlling diastereoselectivity collectively with the allylic alcohol.
