A novel route for the synthesis of 1-aryl-9H-xanthen-9-ones is reported. This methodology involves the condensation of 2-methylchromone with cinnamaldehydes leading to (E,E)-2-(4-arylbuta-1,3-dien-1-yl)-4H-chromen-4-ones. The final steps involved electrocyclization and oxidation of the latter compounds, in an one-pot synthesis, giving the desired 1-aryl-9H-xanthen-9-ones.
报告了一种合成 1-芳基-9H-氧杂蒽-9-酮的新方法。该方法涉及 2-甲基色酮与肉桂醛的缩合,从而得到 (E,E)-2-(4-芳基丁-1,3-二烯-1-基)-4H-色烯-4-酮。最后的步骤包括电环化和氧化后一种化合物,采用一锅合成法,得到所需的 1-芳基-9H-氧杂蒽-9-酮。
