The natural enzyme cytochrome P450 is widely recognised for its unique ability to catalyse highly selective oxygen insertion reactions into unactivated C–H bonds under mild conditions. Its exceptional potential for organic synthesis served as an inspiration for the presented biomimetic hydroxylation approach. Via a remote hydrogen bonding motif a high enantioselectivity in the manganese-catalysed oxygenation of quinolone analogues (27 examples, 18–64% yield, 80–99% ee) was achieved. The site-selectivity was completely altered in favour of a less reactive but more accessible position. A Mn porphyrin complex with a remote hydrogen bonding motif induces a high enantioselectivity in the oxygenation of 3-alkylquinolones. Compared to an achiral Mn complex, the site-selectivity was completely altered in favour of less reactive methylene groups.
