Abstract
C–H bond oxidation is a powerful means for oxygen incorporation in organic molecules. Its use results in fast structural diversification and in a new way of thinking about retrosynthetic disconnections. In this review, we present the application of five metal-catalyzed methodologies for C(sp
3)–H oxidation in the total synthesis of natural and unnatural products, covering the period of 2004–2022.
