Nano-sawdust-OSO3H as a new, cheap and effective nanocatalyst for one-pot synthesis of pyrano[2,3-d]pyrimidines
Sadeghi,Bouslik,Shishehbore
, p. 1801 - 1808 (2015)
An atom-efficient, three-component synthetic methodology has been developed for the preparation of biologically important pyrano[2,3-d]pyrimidines using nano-sawdust-OSO3H as a new catalyst. The reaction involves the use of barbituric acid or t
Green cellulose-based nanocomposite catalyst: Design and facile performance in aqueous synthesis of pyranopyrimidines and pyrazolopyranopyrimidines
Maleki, Ali,Jafari, Abbas Ali,Yousefi, Somayeh
, p. 409 - 416 (2017)
A cellulose-based nanobiocomposite decorated with Fe3O4 nanoparticles was prepared, characterized and applied as an easily recoverable and reusable green nanocatalyst in the synthesis of pyrano[2,3-d]pyrimidine derivatives in water a
