- Diastereoselective synthesis of dihydro-quinolin-4-ones by a borane-catalyzed redox-neutral endo-1,7-hydride shift
-
The borane-catalyzed synthesis of dihydroquinoline-4-ones is developed. The amino-substituted chalcones undergo a 1,7-hydride shift upon Lewis acid activation to form a zwitterionic iminium enolate, which collapses to the dihydroquinoline-4-one scaffold.

- Metal-free oxidation/C(sp3)iH functionalization of unactivated alkynes using pyridine-N-oxide as the external oxidant
-
Externally yours: 2,3-Dihydroquinolin-4(1H)-ones are obtained in moderate to good yields (40-84 %, see scheme) in a metal-free oxidation/C(sp 3)iH functionalization of unactivated aryl alkynes. 2,6-Dichloropyridine-N-oxide is used as an external oxidant. In the reaction, a Bronsted acid, not a metal, plays a key role in the triple CiC bond activation. Copyright
