for site‐selectivefunctionalization of unactivated methylene and methine C−H bonds enabled by an FeII‐catalyzed redox process is described. The mild, expeditious, and modular protocol allows efficient remote aliphatic fluorination, chlorination, amination, and alkynylation of structurally and electronically varied primary, secondary, and tertiary hydroperoxides with excellent functional‐group tolerance
The invention relates to the use of 4-aryl-4-hydroxy-tetrahydropyrans and 3-aryl-3-hydroxy-tetrahydrofurans for the treatment or prevention of chronic obstructive pulmonary disease.
