Synthesis of esters via sp³ C–H functionalisation

Abstract

Oxidative C-O bond formation via sp(3) C-H functionalisation represents an attractive approach for the synthesis of esters. This review focuses on the recent advances of sp(3) C-H bond functionalisation strategies for ester synthesis from unconventional precursors using transition metal/metal free catalysts in combination with various oxidants. Various classes of esters and the mechanisms of their formation are discussed with numerous examples.
