Selective C18-Methyl Oxidation of Sclareol via an Engineered P450 Enables the Synthesis of Spiromyrrhene B.
While selective oxidation of unactivated C-H bonds has emerged as an effective tactic to reshape retrosynthetic strategies in the synthesis of natural products, the primary methyl C-H bonds remain inert and inaccessible to contemporary methods without preinstalled directing groups. Herein, we report a biocatalytic C-H...
