Nano-basic silica as an efficient catalyst for the multi-component preparation of pyrano[2,3-d]pyrimidine derivatives
A high-yield protocol is explored for the synthesis of pyrano[2,3-d]pyrimidines through the multi-component reaction of aromatic aldehydes, 1,3-Dimethylbarbituric acid, and malononitrile using nano-basic silica as an efficient catalyst. The method tolerates various electron-donating and electron-wit...
