Nano-basic silica as an efficient catalyst for the multi-component preparation of pyrano[2,3-d]pyrimidine derivatives
Sheikhan-Shamsabadi, Nafisehsadat,Ghashang, Majid
, p. 19 - 25 (2017)
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 tolerat

We have reported 1,8-diazabicyclo[5.4.0]undec-7-ene catalyzed one-pot synthesis of tetrahydro-4H-chromenes, tetrahydro[b]pyrans, pyrano[d]pyrimidines and 4H-pyrans from aldehydes, active methylene compounds malononitrile/ethyl cyanocacetate and activated C-H acids such as dimedone, 1,3-cyclohexanedione, 1,3-cyclopentanedione, 1,3-dimethylbarbituric acid, and ethyl acetoacetate in water under reflux. The attractive features of this process are mild reaction conditions, reusability of the reaction media, short reaction times, easy isolation of products, and excellent yields.
