Abstract: Abstract A series of 2-amino-7-hydroxy-4H-chromene-3-carbonitriles 4a-l were synthesized through three-component reaction using sodium carbonate as a catalyst. The reaction was carried out in 96% ethanol-water medium (1:20 ratio in volume). Propargyl ether compounds 5a-l of… read more here.
