The first successful preparation of mono- and disubstituted 3,7-dihydroxytropolone involves a four-step synthetic scheme. Thus, bromination of 3,7-dihydroxytropolone (8) followed by permethylation of the resultant products furnished gram quantities of intermediates 13-18. Single or double Suzuki coupling reactions between these permethylated monobromo- and dibromodihydroxytropolone derivatives and
单取代和双取代的3,7-二羟基tropolone的第一个成功制备涉及四个步骤的合成方案。因此,将3,7-二羟基tropolone(8)溴化,然后将所得产物进行全甲基化,得到了克量的中间体13-18。这些全甲基化的单溴代和二溴代二羟基tropolone衍生物与各种硼酸之间的单或双Suzuki偶联反应可提供预期的产物,其脱保护基团可得到所需的化合物1a-u和26a-n,通常收率一般至良好收率。发现Tropolones 1和26是肌醇单磷酸酶的有效抑制剂,IC50值在低微摩尔范围内。在最近描述的3,7-二羟基对苯二酚对酶的新颖抑制方式的背景下讨论了结果。
