Suzuki coupling reactions between 2,4,6-trialkoxyphenylboronic acids and enol triflates have been found to occur in excellent yield, while the use of an enol tosylate failed to give any of the desired product. This coupling reaction has led to the synthesis of a lactone which could serve as a precursor to several calyxin analogues.
已经发现2,4,6-三烷氧基苯基硼酸和烯醇三氟甲磺酸酯之间的Suzuki偶联反应以优异的产率发生,而使用甲苯磺酸甲苯酚未能得到任何所需的产物。该偶联反应导致内酯的合成,该内酯可以用作几种花萼类似物的前体。
