Aminopropyl coated on magnetic Fe3O4 and SBA-15 nanoparticles catalyzed mild preparation of chromeno[2,3-d]pyrimidines under ambient and solvent-free conditions

Abstract

3-Aminopropyltriethoxysilane coated on magnetic Fe3O4 nanoparticles [APTES-MNPs] and 3-aminopropyltriethoxysilane coated on SBA-15 [APTES-(SBA-15)] catalyzed efficiently the one-pot pseudo four-component reaction of salicylaldehydes, malononitrile and secondary amines for preparation of chromeno[2,3-d]pyrimidines under solvent-free conditions at room temperature. The catalysts show environmentally benign character, which can be easily prepared, stored, and recovered without obvious significant loss of activity.
