The natural product (-)-pinolinone was synthesised via a concise route (six steps, 17% overall yield) from 3-acetoxyquinolone, employing an enantioselective intermolecular [2+2] photocycloaddition as the key step. The Royal Society of Chemistry 2014.

Toluene dioxygenase-catalyzed dihydroxylation, in the carbocyclic rings of quinoline, 2-chloroquinoline, 2-methoxyquinoline, and 3-bromoquinoline, was found to yield the corresponding enantiopure cis-5,6- and -7,8-dihydrodiol metabolites using whole cells

Quinoline-2-carboxylic acid derivatives cap the N-terminal of several natural cyclic peptides with antitumoral activity. A new and convenient route for the preparation of 3-hydroxyquinoline-2-carboxylic acid is discussed. The preparation of the title compound is accomplished by a four-step procedure from 3-hydroxyquinoline via MOM protection of the hydroxyl group, followed by a 1,2-addition of methyllithium to the quinoline ring with concomitant oxidation, and, finally, a two-step oxidation procedure for the transformation of the methyl group to the carboxylic acid along with removal of the MOM group. Furthermore, different attempts to its preparation led to other interesting quinolines, such as 2-chloro-3-hydroxyquinoline-4-carboxylic acid and a protected 3,3′-dihydroxy-2,2′-biquinoline.
Directed ortho-Lithiation of Chloroquinolines. Application to Synthesis of 2,3-Disubstituted Quinolines
Marsais, F.,Godard, A.,Queguiner, G.

2-, 3- and 4-Chloroguinolines were selectively lithiated at low temperature by lithium diisopropylamide at the more acidic C-3, C-4 and C-3 positions respectively.Reaction of 2-chloro-3-lithioquinoline with electrophiles led to various 2,3-disubstituted quinolines.The versatility of this functionalization methodology is enhanced by the C-2 halogen reactivity towards oxygen or nitrogen nucleophiles.So, a great variety of 2,3-disubstituted quinolines were synthesized, such as 2-chloro, 2-alkoxy, 2-aminoquinolines or 2-quinolones bearing an hydroxy, carbonyl (aldehyde, ketone or carboxylic acid), iodo, trimethylsilyl or boronic acid moiety at the C-3.Some of the resulting 2,3-disubstituted synthons were annelated to tetracyclic polyaromatics, which possess the xanthone or indole structure.This could be achieved via further functionalization of the quinoline ring either by SNAr2 or heteroaromatic cross-coupling reactions, after the first directed-lithiation step.
