“…2-aryl-4H-chromene was prepared and its prominent α-glucosidase inhibitory activities were studied 13 . 2-Amino-4H-Chromenes possess a broad range of medicinal activities 14 . Vinyl-2Hchromene-3-carbonitriles, prepared by Knoevenagal condensation were found to have enhanced optical properties and could be used as dyes 15 .…”

A catalyst-free synthetic strategy to chromene carbonitriles by Multi-Component Reaction of pyrazole aldehydes, 5,5-dimethylcyclohexane-1,3-dione and malononitrile with ethanol, at room temperature is reported. Screening of solvents and purification of the compounds were also performed. The newly synthesized novel compound’s (4H-chromene-3-carbonitriles) structures were authenticated by the spectral techniques viz. (1H , 13C)Nuclear Magnetic Resonance, FT-IR, and LC-MS analysis.

A simple and efficient approach for the general synthesis of 4-(2,2-diarylvinyl)quinolines 5 and 4-(2,2-diarylvinyl)-2H-chromenes 6 has been developed using Fe(III)-catalyzed intramolecular annulations of homopropargyl substrates 1 and 2, respectively. The high yields (up to 98%) achieved using simple substrates, an environmentally benign low-cost catalyst, and less hazardous reaction conditions make the methodology inherently attractive.
