Enzymatic C H functionalizations for natural product synthesis

Direct functionalization of CH bond is rapidly becoming an indispensible tool in chemical synthesis. However, due to the ubiquity of CH bonds, achieving site-selective functionalization remains an arduous task, especially on advanced synthetic intermediates or natural products. In contrast, Nature has evolved a multitude of enzymes capable of performing this task with extraordinary selectivity, and the use of these enzymes in organic synthesis may provide a viable solution to contemporary challenges in site-selective functionalization of complex molecules. This review covers recent applications of enzymatic CH functionalization strategies in natural product synthesis, both in the context of key building block preparation and late-stage functionalization of advanced synthetic intermediates.
