Curcumin 3,4-dihydropyrimidinones/thiones/imines have been synthesized using one-pot cyclocondensation of curcumin with substituted aromatic aldehydes and urea/thiourea/guanidine in the presence of chitosamine hydrochloride as a biodegradable and nontoxic catalyst under solvent-free microwave irradiation. The synthesized product was purified by crystallization from ethanol and the process does not involve any hazardous solvent. All the synthesized curcumin derivatives 4a–o were screened for antioxidant and anti-inflammatory activity. Biological activity data of the synthesized showed that most of the synthesized compounds exhibited greater antioxidant and anti-inflammatory activity than curcumin.
