An efficient direct aerobic oxidative olefination of the methyl groups of 2-methylquinolines with benzylamines in the presence of a rare-earth-metal Lewis acid catalyst to give 2-styrylquinolines was successfully developed. Preliminary mechanistic studies revealed that the oxidative olefination reaction proceeds through a Lewis acid-catalyzed 2-methylquinoline-aldehyde condensation and an amine-aldehyde condensation.

An oxidative olefination reaction between aliphatic primary amines and benzylic sp3 C-H bonds has been achieved using N-bromosuccinimide as catalyst and tert-butyl hydroperoxide as oxidant. The olefination proceeds under mild metal-free conditions through direct deamination and benzylic C-H bond activation, and provides easy access to biologically active 2-styrylquinolines with (E)-configuration.

Bioactive azaarene-substituted lactic acids, β-hydroxy esters, 3-hydroxy-2H-indol-2-ones, and 2-alkenylazaarenes were prepared in moderate-to-excellent yields via C(sp3)-H functionalization of methyl azaarenes with carbonyl compounds in the presence of iron(ii) acetate as an inexpensive, nontoxic, efficient catalyst. The application of this atom-, step-economic, and environmentally friendly method was demonstrated by a gram-scale synthesis of 3-[(E)-2-(7-chloroquinolin-2-yl)vinyl]benzaldehyde, a key intermediate of leukotriene receptor antagonist (Montelukast).
