A one-pot synthesis of quinolines via molecular iodine-catalyzed and air-mediated tandem condensation/imino-Diels–Alder/isomerization/oxidation of simple readily available amines, aldehydes, and alkynes has been developed. This methodology was extended to synthesize quinazolines from two molecules of amines and two molecules of glyoxalates.
A one-step synthesis of 4-arylquinoline-2-carboxylates along with their antiprotozoal activity against the pathogenic parasite Toxoplasma gondii is reported. Mechanistic insights into the role of Lewis acid (silver triflate) versus Bronsted acid (triflic acid) catalysis are revealed clarifying aspects of the mechanism of the quinoline synthesis.

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 Ce(III)-catalyzed, visible-light-induced aerobic oxidative dehydrogenative coupling/aromatization reaction between glycinederivatives and alkenes has been developed, which provides an efficient approach for the synthesis of quinolinederivatives and post-modification of oligopeptides containing glycine residues under mild conditions without the need for external photosensitizers.
