A highly efficient strategy for the enantioselective oxidation of methylene C–H of spirocyclic oxindoles and dihydroquinolinones has been established, in which an earth-abundant manganesecatalyst and hydrogenperoxide are used. Noteworthy, the manganesecatalyst can be applied to the asymmetric hydroxylation of spirocyclic 2,3-dihydroquinolin-4-ones with 94–99% ee.

Disclosed are pharmaceutical compositions and formulations comprising benzoquinoline derivatives having formulas (I) to (V). In formula (I), X i selected from the group consisting of O, S, CH2, CH2-CH2, C=O or NR8; Z is C or N; R1, R2, R3, and R4 are independently selected from the group consisting of hydrogen, halogen, linear or branched chain lower alkyl, alkenyl, alkynyl, alkoxy or acyl; X-RA and R3, or R3 and R4 are optionally linked together to form a ring or a salt thereof, and a pharmaceutically acceptable carrier or diluent. Also disclosed are methods of inhibiting bacterial growth, comprising the administration of formulations comprising the compounds of formulas (I) to (V).
