Iron-Promoted Tandem Reaction of Anilines with Styrene Oxides via C–C Cleavage for the Synthesis of Quinolines
摘要:
A novel iron-promoted tandem reaction of anilines with styrene oxides via C-C cleavage and C-H activation has been developed. The reaction utilizes an inexpensive FeCl3 as promoter and is suitable for forming a variety of 3-aryiquinolines from the simple and readily available starting materials.
[3+1+1+1] Annulation to the Pyridine Structure in Quinoline Molecules Based on DMSO as a Nonadjacent Dual-Methine Synthon: Simple Synthesis of 3-Arylquinolines from Arylaldehydes, Arylamines, and DMSO
A [3+1+1+1] annulation of arylamines, arylaldehydes, and dimethyl sulfoxide (DMSO) to the pyridine structure in quinolines using DMSO as a nonadjacent dual-methine (═CH−) synthon is disclosed. In this annulation, arylamines provide two carbon atoms and one nitrogen atom, arylaldehydes furnish one carbon atom, and DMSO provides two nonadjacent methines (═CH−) to the pyridine ring in quinoline molecules
Solvent-free and room temperature synthesis of 3-arylquinolines from different anilines and styrene oxide in the presence of Al<sub>2</sub>O<sub>3</sub>/MeSO<sub>3</sub>H
A highly efficient, simple and environmentally friendly synthesis of 3-arylquinolines has been developed in the presence of Al2O3/MeSO3H via one-pot reaction of anilines and styrene oxide. This methodology provides very rapid access to 3-arylquinolines in good to excellentyieldsundersolvent-freeconditions at roomtemperature in air.

3-Haloquinolines can be functionalized via a palladium-catalyzed desulfitative coupling of arylsulfinates. This method tolerates substitution upon the aromatic ring and shows good selectivity toward variously substituted aromatic rings. (C) 2013 Elsevier Ltd. All rights reserved.
