摘要
An efficient and simple protocol for the one-pot three-component synthesis of 3,4-dihydropyrano[3,2-c]chromenes 4 is described, via the reaction of aromatic aldehydes 1, malononitril 2 and 4-hydroxycumarin 3 in the presence of 10 mol% of piperidine as catalyst, in ethanol (EtOH) at ambient temperature. Short reaction times, environmentally friendly procedure and excellent yields are the main advantages of this procedure, which makes it more economical than other environment friendly methods.
