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.

A one-pot procedure for the preparation of substituted quinolines from substituted o-nitrotoluenes with electron-withdrawing groups and olefins (acrylic esters and acrylonitriles) using a cesium catalyst under mild reaction conditions is reported. The process involves a [2+4] cycloaddition mechanism.

: In recent years, reductive dehydration of primary nitro compounds has been demonstrated as an attractive and alternative approach for the direct synthesis of nitriles. Although scattered information on the conversion of alkyl nitrites and/or nitroalkanes to the corresponding nitriles has been reported in the literature, a research paper describing comprehensive information at one place is scarce. The present review has attempted to focus on the uncatalyzed as well as catalyzed reductive dehydration of nitro compounds directly into nitriles in the presence of dehydrating reagents. Non-metal and metal-catalyzed dehydration of nitro compounds and the use of radical chemistry in accessing nitriles have been highlighted in this review article.
