The first total synthesis of bruceol has been achieved using a biomimetic cascade cyclization initiated by a stereoselective Jacobsen–Katsuki epoxidation (and kinetic resolution) of racemic protobruceol‐I. A bacterial cytochrome P450 monooxygenase was also found to catalyze the conversion of protobruceol‐I into bruceol. The first full analysis of the NMR data of natural bruceol suggested that “isobruceol”
通过仿生的protobruceol-I的立体选择性Jacobsen-Katsuki环氧化(和动力学拆分)引发的仿生级联环化,实现了布鲁索尔的第一个全合成。还发现一种细菌的细胞色素P450单加氧酶可催化将protobruceol-I转化为bruceol。对天然布鲁赛尔的NMR数据进行的第一个完整分析表明,“异bruceol”是一种先前无法识别的
天然产物,也从Philotheca brucei中分离出来。
异丁醚醇的重新分离,合成和X射线分析证实了这一点。总共已经以高度不同的方法合成了苯丁
酚的八个立体异构体和结构异构体。
