The late-stage Csingle bondH oxofunctionalization of (-)-ambroxide with H2O2 in the presence of bioinspired honheme Mn complexes is reported. Adjusting the ligand architecture and absolute chirality, as well as tuning the reaction solvent, allows switching the catalysts’ selectivity between biosynthetic-like and bioorthogonal modes, thus directing the reaction towards either (+)-sclareolide or 2α-hydroxyambroxide, respectively. This opens the ways to 2,12-dihydroxyambroxide, 2α-hydroxysclareolide, ambroxide-2-one, ambroxide-2,12-dione, and several other, including previously unavailable, oxidized metabolites of (-)-ambroxide in synthetically meaningful yields, using the same catalyst systems.
