Sequential Reduction

An efficient iron/acetic acid system-mediated reductive cyclization reaction of substituted 2-aryl-3-nitro-2H-chromenes with substituted 2-nitrobenzaldehydes for the synthesis of 6-aryl-6H-chromeno[3,4-b]quinolines was developed. This reaction involves the sequential reduction, hydrolysis, aldol condensation, intramolecular addition, and the nucleophilic addition of substituted 2-aryl-3-nitro-2H-chromenes with substituted 2-nitrobenzaldehydes to give the corresponding 6H-chromeno[3,4-b]quinolines. This transformation provides a straightforward synthetic protocol for constructing substituted 6H-chromeno[3,4-b]quinoline derivatives. The structures of three typical products were confirmed by X-ray crystallography.

Facile Route

A facile route for the preparation of 1,2-diaryl-4-arylmethylene-2-imidazolin-5-ones was established by the direct interaction of primary aromatic amines with 2-(m-tolyl)-4-arylmethylene-2-oxazolin-5-ones in acetic acid containing catalytic amounts of sodium acetate. The same imidazolones were also obtained by cyclization of the aryl- carboxamides of α-arylcarboxamido-β-arylacrylic acids under the same reaction conditions. A possible reaction mechanism was discussed.
