Scalable and diastereoselective synthetic approach to 4,4-difluorospiro[2.2]pentan-1-yl derivatives by the difluorocyclopropanation of (2-methylenecyclopropyl)methanol and further chemical modifications were disclosed. Structural features, pKa, logP, and aqueous solubility of the products were established and compared with those of non-fluorinated and 2,2-difluorinated analogs, as well as monocyclic
