摘要

Abstract Different 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 studies towards the synthesis of fused quinazolinones yielded ...
