Malonicacid derivatives have been successfully applied in a Ag-catalyzed decarboxylative fluorination reaction, providing an unprecedented route to either gem-difluoroalkanes or α-fluorocarboxylic acids by the judicious selection of base and solvent. This reaction features the use of readily available starting materials, tunable chemoselectivity and good functional group compatibility as well as gram-scale

The present invention is directed to compounds that are inhibitors of cysteine proteases, in particular, cathepsins B, K, L, F, and S, and are therefore useful in treating diseases mediated by these proteases. The present invention is directed to pharmaceutical compositions comprising these compounds and processes for preparing them.
The title compounds were hydrogenolyzd over PdO or Raney nickel. The C2–C3 bond of the cyclopropane ring underwent cleavage exclusively over the both catalysts. The contribution of the fluorine substituent to the lengthening and weakening the C2–C3 bond of the cyclopropane ring seems to become a dominant factor in the regioselectivity.
