In our previous studies, we focused on developing transition metal-free radical borylation reactions. We therefore turned our interest towards the use of amidyl radicals for remote C-H bond (γ-position of a carbonyl compound) borylation reaction (Scheme 2d), which, to our knowledge, has not been realized previously. It is known that α-C-H bond of carbonyl compounds is acidic, and can be simply activated by basic conditions. For β-C-H bond, the strategy of oxidation/Michael addition can be implemented. Despite these advances in the development of the approaches to functionalization at α-and β-positions of carbonyl compounds, for the direct γ-C-H functionalization, only a few of examples have been reported
