  一种恶拉戈利的合成方法

  摘要：

  本发明提供了一种恶拉戈利的合成方法，包括由化合物5与化合物10经过缩合完成N‑烷基化反应得到化合物11，再碱解得到恶拉戈利12。本发明还公开了化合物5的两种合成方法：方法一将5‑溴‑6‑甲基嘧啶‑2,4(1H,3H)‑二酮化合物1和2‑(溴甲基)‑1‑氟‑3‑(三氟甲基)苯化合物2通过缩合反应得到中间体3，再进行偶联反应；方法二将1‑卤代‑3‑氟‑2‑甲氧基苯6与乙酰乙酸酯7通过偶联反应先得到化合物8，再与化合物9经缩合环化反应；这些改进都极大地缩短了路线步骤，提高了路线效率，并且可以避免使用贵金属催化剂，极大地降低了工艺成本。该路线操作简单，不仅总收率较高，得到的产品纯度也较高，适合放大生产。

  of biphenyls, analogs of aglycone of natural product fortuneanoside E, were prepared using Suzuki–Miyaura cross-coupling and selective magnesium iodide demethylation/debenzylation, and their mushroom tyrosinase inhibitory activity was evaluated. Most of the 4-hydroxy-3,5-dimethoxyphenyl biphenyl compounds (series II, 20–36) were in general more active than 3,4,5-trimethoxyphenyl biphenyl compounds (series

  使用铃木-Miyaura交叉偶联和选择性碘化镁去甲基/去苄基作用，制备了两个新的联苯系列，即天然产物苦瓜子苷E糖苷配基类似物，并评估了其对蘑菇酪氨酸酶的抑制活性。通常，大多数4-羟基-3,5-二甲氧基苯基联苯化合物（II系列，20–36）比3,4,5-三甲氧基苯基联苯基化合物（I，1-19）更具活性。结构-活性关系研究表明，单糖取代基（例如葡萄糖）不是必需的，并且4-羟基-3,5-二甲氧基苯基部分的存在对于抑制活性至关重要。在合成的化合物中，化合物21（IC 50 = 0.02 mM）是活性最高的一种，其活性比金银花皂苷E（IC 50  = 0.14 mM）高7倍，比熊果苷（IC 50  = 0.21 mM）高10倍，被称为有效的酪氨酸酶抑制剂。通过Lineweaver-Burk图分析的抑制动力学表明，化合物21是竞争性抑制剂（K i  = 0.015 mM）。
