Silica (SiO2) catalyzed one-pot synthesis of 4-[(dialkylamino)methyl]-1,7-diphenylhepta-1,6-diene-3,5-dione. An expeditious synthesis under microwave irradiation method for curcumin Mannich base derivatives are known for its biological activity. Curcumin is naturally occurring yellow pigments isolated from Curcuma longa, structurally it is polyphenolic compounds consisting spectacular biological activity. However, clinical utility of curcumin is limited due to its poor bioavailability. Present methodology offers silica catalyzed one pot, productive technique to obtain curcumin Mannich base. Both, conventional and microwave irradiation methods were found productive. The final products were characterized by 1H NMR.


Curcumin, Mannich reaction, One-pot, Conventional and Microwave irradiation method.
