Abstract: Abstract An efficient synthesis of new aminodimethyl(methylsulfonyl)dihydropyrido[2,3-d]pyrimidinedione derivatives via the three components reaction of 2-methanesulfonylacetonitrile, 1,3-dimethyl-6-amino-uracil, and aromatic aldehydes in the presence of [HO-(CH2)2-NH2][CH3CO2H] and Fe3O4@SiO2@[O-(CH2)2-NH2][CH3CO2H] as novel heterogeneous magnetic nanocatalyst was described. The Fe3O4@SiO2@[O-(CH2)2-NH2][CH3CO2H]… read more here.
