Webb21 aug. 2024 · Site selectivity and stereocontrol remain major challenges in C–H bond functionalization chemistry, especially in linear aliphatic saturated hydrocarbon scaffolds. We report the highly enantioselective and site-selective catalytic borylation of remote C(sp 3 )–H bonds γ to the carbonyl group in aliphatic secondary and tertiary amides and esters. WebbThis group is related to the group ‘Esters from linear saturated dicarboxylic acids and of linear or cyclic aliphatic alcohols’. Some of the substances from both groups belong to the same registrant’s category(ies) such as the ‘Polyfunctional liphatic Ester (PFAE) linear’ category and the ‘Dibasic ester’ category.
