Reductive Ring Opening of 3,5-Bis(2-arylethenyl)isoxazoles with Molybdenum Hexacarbonyl: A Novel Route to Symmetrical and Unsymmetrical Curcumin Derivatives
نویسندگان
چکیده
Curcumin derivatives were successfully synthesized from 3,5-dimethylisoxazole by lateral metalation and condensation with various aromatic aldehydes sequentially at C5and C3-methyl groups. After dehydration, further transformation of isoxazole ring to b-diketone moiety was accomplished by reductive ring opening using molybdenum hexacarbonyl [Mo(CO)6] and subsequent simple acidic hydrolysis. key words : Curcumin derivatives, Reductive ring opening, Molybdenum hexacarbonyl, Lateral metalation
