An approach to the preparation of gem-difluorocyclopentane/hexane-derived carboxylic acids and amines is described. Whereas for 3,3-difluoro-substituted cycloalkanones, straightforward deoxofluorination of the corresponding ketoesters led to the target compounds, in the case of 2,2-difluoro isomers, the bypass or alternative routes were necessary.

α-Methylene carbonyl compounds are regioselectively prepared by the reaction of α-nitroketones or α-nitroesters with 37percent formaldehyde in the presence of a catalytic amount of weak bases followed by acetylation, denitration with Bu3SnH, and elimination of acetic acid.
