Cyclic β,β‐difluoro‐carbonyl compounds have a venerable history as drug discovery leads, but limitations in the synthesis arsenal continue to impede chemical space exploration. This challenge is particularly acute in the arena of fluorinated medium rings where installing the difluoromethylene unit subtly alters the ring conformation by expanding the internal angle (∠C−CF2−C>∠C−CH2−C): this provides a handle to modulate physicochemistry (e.g. p
