corresponding 2,3-dihydro-4(1H)-quinolones via acyl migration and N–CO fission. In the case of 1-(3-substituted phenyl)azetidin-2-ones, two positional isomeric products, 5- and 7-substituted 2,3-dihydro-4(1H)-quinolones were obtained. 4-Methyl-, 4-ethoxycarbonyl-, and 4-piperidin-2yl-1-arylazetidin-2-ones and their analogues were also converted into the corresponding 2-substituted 2,3dihydro-4(1H)-quinolones

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.
Cobalt-Catalyzed Diborylation of 1,1-disubstituted Vinylarenes: A Practical Route to Branched <i>gem</i>
-Bis(boryl)alkanes

vinylarenes underwent this transformation to produce the corresponding gem‐bis(boryl)alkanes in modest to high yields. This cobalt‐catalyzed reaction can be readily conducted on a gram scale without the use of a dry box and represents a practical and effective approach to prepare a wide range of branched gem‐bis(boryl)alkanes.
