The total synthesis of biologically active pyranoflavone natural products 1 and 2 was carried out starting from 2H-pyran. The synthesis of pyranochalcone natural products, lonchocarpin (9) and 4-hydroxylonchocarpin (10), and their derivatives 30-32 is described. This synthetic route also provides biologically interesting materials such as β-tubaic acid (24), desmethyl isoencecalin (25), and isoencecalin (27).
从2H-吡喃出发,完成了生物活性吡喃黄酮天然产物1和2的全合成。本文描述了吡喃查尔酮天然产物,扁柄草素(9)和4-羟基扁柄草素(10)及其衍生物30-32的合成。该合成路线还提供了生物学上有趣的物质,如β-图贝酸(24)、去甲基异黄皮树脂酚(25)和异黄皮树脂酚(27)。
