saturated (hetero)cyclic substituents-advanced sp3-enriched fluorinated buildingblocks for drug discovery-were developed on up to 10 g scale. The key intermediates-novel sp3-enriched β-bromo-α,α-difluoroketones and α-fluoroketones-are valuable for synthetic and medicinal chemistry per se. Most of the 19 synthesized buildingblocks were lead-oriented.
