with unactivated alkenes has been accomplished. This visible light-driven protocol has been successfully applied to a broad scope of glycine esters and simple alkenes, giving rise to diverse substitutedquinoline derivatives in 18–84% yield under mild (at room temperature under air atmosphere) and operationally simple reaction conditions.

The synthesis of a variety of substituted quinolines from N-alkyl anilines by a one-pot dehydrogenative Povarov/oxidation tandem reaction with mono- and 1,2-disubstituted aryl and alkyl olefins was developed. A simple protocol using cheap and benign iron(III)chloride as the Lewis acid catalyst and a TEMPO oxoammonium salt as a nontoxic, mild, efficient oxidant is reported.
Visible-light-enabled aerobic oxidative C<sub>sp3</sub>–H functionalization of glycine derivatives using an organic photocatalyst: access to substituted quinoline-2-carboxylates
A practical visible-light-induced aerobic oxidative dehydrogenative coupling reaction of glycine derivatives with olefins has been developed to efficiently synthesize quinoline-2-carboxylates. This metal-free process proceeds smoothly under mild conditions and exhibits good tolerance of functional groups. Given the low cost of the catalyst and feedstock materials, the mild reaction conditions and the

A gold‐oxazoline complex‐catalyzeddehydrogenative Povarov/oxidation tandem reaction for the synthesis of decorated quinolines has been developed from glycine derivatives and alkenes. The reaction performs under mild reaction conditions in the presence of oxygen as the oxidant and features a broad substrate scope and excellent functional group tolerance.

A practical and economical K2S2O8-mediated oxidative cross-dehydrogenative coupling of N-aryl glycine derivatives with olefins has been established, affording structurally diverse quinoline-2-carboxylates in good to high efficiency. The low cost, negligible toxicity, and ease of handling of K2S2O8 combined with the absence of hazardous byproducts and the easy workup consisting of simple filtration are attractive based on economic and environmental factors.
