Diversity: A range of substituted 2-alkylquinolines can be prepared in a general and efficient synthetic approach that employs mild reaction conditions (see scheme). The synthesis is based on a sequential palladium-catalyzed Ci-N and Ci-C bond formation, followed by palladium-catalyzed aromatization, and results in the formation of the desired compounds in one step.

Synthesis of Quinolines and 2H-Dihydropyrroles by Nucleophilic Substitution at the Nitrogen Atom of Oxime Derivatives

Isomerization of oxime derivatives was researched in detail to find out the methods for the syn-anti isomerization of O-substituted oximes. Based on these findings were developed simple methods for the preparation of aza-heterocycles from both stereoisomers of oximes. Quinolines were synthesized from β-aryl ketone oximes by treatment with trifluoroacetic anhydride and 4-chloranil. γ,δ-Unsaturated O-methoxyacetyloximes were transformed to 2H-dihydropyrroles by reaction with methoxy-acetic acid.
Transformation of oximes of phenetyl ketone derivatives to quinolines and azaspirotrienones catalyzed by tetrabutylammonium perrhenate and trifluoromethanesulfonic acid

Phenethyl ketone oximes are converted to quinolines by the treatment with tetrabutylammonium perrhenate, trifluoromethanesulfonic acid, and chloranil in refluxing 1,2-dichloroethane. Azaspirotrienones can be synthesized from p-hydroxyphenethyl or 3-(p-hydroxyphenyl)propyl ketone oximes by applying the above method. Thus prepared azaspirotrienones are converted to quinolines by acid treatment.
Synthesis of Quinolines via Intramolecular Cyclization of Benzylacetone Oxime Derivatives Catalyzed with Tetrabutylammonium Perrhenate(VII) and Trifluoromethanesulfonic Acid

, p. 5 - 6 (2007/10/02)
Intramolecular cyclization reaction on the nitrogen atom of benzylacetone oxime derivatives, which have electron donating group(s) on the phenyl group, proceeds by treatment with tetrabutylammonium perrhenate, trifluoromethanesulfonic acid, and 4-chloranil in refluxing 1,2-dichloroethane to afford quinoline derivatives in good yield.
