A novel route to the synthesis of cyclopropane derivatives is described. 1, 1-Dimethyls in 2- (1, 1-dimethylalkyl) dimethyloxazolines are first converted into 1, 3-diiodide derivatives via Pd-catalyzed sequential CH activation and then radically cyclized to provide 2-(1- alkylcylclopropyl) dimethyloxazolines. The use of EtOAc as a solvent is crucial for the diiodination of the functionalized substrates.
