7-methyl-4-nitro-1-oxohydrindene derivatives. Functional group elaborations of these intermediates lead to a series of the title compounds, which could be readily converted to the tricyclic moieties of strigol and its analogues of biological importance.
提出了一种改进的环化顺序,该方法利用了5-硝基戊烷-2-一酮和环戊-2-烯酮二酯的一锅式环化反应,从而获得了7-甲基-4-硝基-1-氧代氢吲哚衍生物。这些中间体的官能团修饰产生了一系列标题化合物,这些标题化合物可以容易地转化为strigol及其生物学重要性类似物的三环部分。
