First Total Synthesis of A New 5-Deoxyflavone

【摘要】:正 A novel 5-deoxyflavone compound, 7, 8-dimethoxy-3', 4'-methylene-dioxyflavone (1), was in 2002 isolated from the root bark of Albizia Odoratissima .The compound 1 was preparaed from pyrogallic acid (2) and piperonal (5) in four steps (Scheme 1) .The spectroscopic data (1H NMR, 13C NMR, MS and IR) of 1 were in good agreement with those of natural product.
