(Diagram presented) 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 C-H 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.

A monoprotected aminoethyl amine chiral ligand based on an ethylenediamine backbone was developed to achieve Pd-catalyzed enantioselective C(sp3)-H arylation of cyclopropanecarboxylic and 2-aminoisobutyric acids without using exogenous directing groups. This new chiral catalyst affords new disconnection for preparing diverse chiral carboxylic acids from simple starting materials that are complementary to the various ring forming approaches.
