in the synthesis are site selective bromination reaction followed by Suzuki coupling reaction in very good yield. The structural assignment of the bromo derivative was determined utilizing 2D-HMBC and NOEs NMR techniques. An efficient method for the preparation of odoratine, a naturally occurring isoflavone, has been described. 8-substituted odoratine derivatives were prepared via the Suzuki coupling
为8-取代odoratine [(3-(3-制备一种有效的方法',4 ' -methylenedioxyphenyl)-5,6,7,8--trimethoxyisoflavone]衍生物,结构上类似于glaziovianin A,已知的细胞毒性物质,进行了说明。合成的关键步骤是定点溴化反应,然后以非常好的收率进行Suzuki偶联反应,使用2D-HMBC和NOEs NMR技术确定了溴衍生物的结构。 已经描述了一种用于制备奥他汀的有效方法,奥他汀是一种天然存在的异黄酮。通过Suzuki偶联反应制备了8-取代的奥他汀衍生物。探索了定点溴化反应以获得偶联反应所需的关键中间体。
