From Ketones, Amines, and Carbon Monoxide to 4‑Quinolones: Palladium-Catalyzed Oxidative Carbonylation
A novel
method of palladium-catalyzed oxidative carbonylation of ketones,
amines, and carbon monoxide for the synthesis of 4-quinolones has
been developed. This protocol provides a straightforward route to
construct useful 4-quinolone derivatives from inexpensive chemicals
Electro-oxidative C(sp3)–H Amination of Azoles via Intermolecular Oxidative C(sp3)–H/N–H Cross-Coupling
A method for electrooxidative
CÂ(sp3)–H amination via intermolecular
oxidative CÂ(sp3)–H/N–H cross-coupling has been developed
under metal- and oxidant-free conditions. The CÂ(sp3)–H bonds
adjacent to oxygen, nitrogen, and sulfur atoms could all react smoothly
with various amines to give the corresponding products with moderate
to good yields (30–93%). In addition, the CÂ(sp3)–H bonds
of benzylic and allylic are also tolerated in this reaction. A preliminary
mechanistic study indicates that the C–H cleavage of tetrahydrofuran
is probably not involved in the rate-determining step
