摘要：

An efficient, one-pot synthetic protocol toward 1,4-dihydropyridine derivatives starting from 1,1-bis(methylthio)-2-nitroethylene, 1,n-diamine, malononitriles, and either isatins or aromatic aldehydes has been developed. The reaction proceeds under solvent-free conditions in the presence of nano-Fe3O4-GO-SO3H as a solid acidic catalyst to give the title compounds in good yields. [GRAPHICS] Sulfonic functionalized magnetic graphene oxide catalyzed one-pot four components synthesis of 1,4-dihydropyridine derivatives under solvent-free conditions.
