SYNTHESIS AND COMPARATIVE STUDY OF CURCUMINOID ANALOGUES BY CONVENTIONAL AND NON-CONVENTIONAL METHODS

Conventionally, Starting as an vanillin condensed with acetyl acetone by using tributyl borate, boric anhydride and butyl amine then reaction mixture was allowed to stand for overnight at room temperature, after workup it convert yellowish product. Similarly, Non-conventionally, Acetyl acetone, boric acid, anhydrous Sodium sulfate mixed in toluene then substituted aromatic aldehydes added with n-BuNH2, formed mixture irradiated to MWI, after workup, final compound was collected. Second method is environmentally benign gives good yields of curcumin analogues under microwave condition. The reaction performed in less time of reaction, cleaner, no side product, good to excellent yield of product.
