An unprecedented remote amide-directed palladium-catalyzedintermolecularhighly selective benzylic C-H amination with N-fluorobenzenesulfonimide is developed, which represents the first direct benzylic C-H amination with a non-nitrene nitrogen source. This methodology provides a novel approach to circumvent the common ortho aromatic C-H selectivity in directed palladium catalyzed C-H functionalization
The present invention is directed to quinolinone compounds which are useful as therapeutic agents for the treatment of central nervous system disorders associated with phosphodiesterase 2 (PDE2). The present invention also relates to the use of such compounds for treating neurological and psychiatric disorders, such as schizophrenia, psychosis or Huntington's disease, and those associated with striatal hypofunction or basal ganglia dysfunction.

A novel annulation reaction of readily available tolylamides was catalyzed by Cu(OTf)2 in the presence of Selectfluor and water through successive intermolecular CH activated dehydrogenativecross‐coupling reactions of benzylic methyl C(sp3)H and aromatic C(sp2)H bonds, and subsequent intramolecular CO bond formation (see scheme).
