Selective degradation of block copolymer templates and backfilling the open mesopores is an effective strategy for the synthesis of nanostructured hybrid and inorganic materials. Incorporation of more than one type of inorganic material in orthogonal ways enables the synthesis of multicomponent nanomaterials with complex yet well-controlled architectures; however, developments in this field hav...

In the presence of IR irradiation by the use of solid support montmorillonite KSF, under solvent free conditions four component aldehyde, Dione, Meldrum acid and ammonium acetate react for the formation of 1, 4 dihydropyridine derivatives. This is a greener method and one pot synthesis. Minimum reaction time and higher yield are the advantages of this process. The product can be purifying by ch...
