Photocatalysis‐Triggered Click Reactions and Applications

European Journal of Organic Chemistry, EarlyView.
Photoclick chemistry offers broad applications ranging from materials science to bioconjugation, with precise spatiotemporal control over click reactions. Initially limited to UV activation, recent advances have extended photoclick processes to the visible and NIR regions thanks to the photocatalysis.

Bromonitroalkanes in Organic Synthesis

European Journal of Organic Chemistry, EarlyView.
α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical, carbanion, and carbocation synthons. This mini‐review summarizes the different reaction modes and highlights recent developments in thermal and photochemical processes. α,α‐Bromonitroalkanes (BNAs) exhibit chameleon‐like reactivity, serving as carbene, radical,

Axial Chirality Control Through Palladium‐Catalyzed Alkenylation Reactions for the Atroposelective Synthesis of 4‐Arylquinolin‐2‐ones

European Journal of Organic Chemistry, EarlyView.
Palladium(II)‐catalyzed intramolecular C─H alkenylation of cinnamides allows the atroposelective synthesis of axially chiral 4‐arylquinolones, with the chirality being installed by ring formation. DFT studies have shown that the reaction proceeds by prior activation of the alkene and the enantioselectivity is determined during the β‐hydride elimination

Mo‐Catalyzed Synthesis of 3‐Substituted Quinolines From Nitroarenes and Aldehydes

European Journal of Organic Chemistry, EarlyView.
A one‐pot Friedländer synthesis of 3‐substituted quinolines from readily available o‐nitrobenzaldehydes and aldehydes or acetals has been developed under dioxomolybdenum(VI) catalysis. Pinacol acts as a benign reductant, enabling in situ nitroarene reduction and annulation without isolation of o‐aminobenzaldehydes and provides access to diverse ...

Chiral Copper(II) Complex‐Catalyzes Site‐Selective Monofunctionalization of Levoglucosan Analogs

European Journal of Organic Chemistry, EarlyView.
A chiral copper‐catalyzed strategy for the site‐selective functionalization of levoglucosan and its analogs is reported. Using CuCl2 in combination with a chiral bis(oxazoline) ligand, selective functionalization of the O2 or O4 hydroxyl group was achieved, with the regioselectivity controlled by the ligand configuration.
