approaches towards the synthesis of auranthine have been investigated. A completed synthesis of 3-[2-(4-oxo-3,4-dihydro-quinazolin-2-yl)-3,4-dihydro-1H-benzo[e][1,4]-diazepine-2,5-dione, an auranthine precursor, which after dehydration with 50% propylphophonic acid anhydride solution in ethl acetate and DMA gave a C-acetyl derivative of aurnathine. Additionally studiestowards the synthesis of fused
