the first naturally occurring carbazole alkaloids with antituberculosis (anti-TB) activity, clausine K and micromeline, a study on the structure–activity relationships for anti-TB-active carbazolederivatives has been carried out. The 6-oxygenated carbazoles glycozoline and glycozolinine show antibiotic activity towards several microorganisms. The 7-oxygenated carbazole siamenol exhibits anti-HIV activity

the efficient iron-mediatedtotalsynthesis of clausine O, clausine H (clauszoline-C) and anti-HIV active 7-methoxy-O-methylmukonal and clausine K (clauszoline-J). Consecutive C–C and C–N bond formations between 3-methoxy-4-methylaniline and a cyclohexadienyliumiron complex salt afforded 2,7-dimethoxy-3-methylcarbazole, which served as common intermediate en route to the four alkaloids.
我们描述了高效铁介导的 clausine O、clausine H(clauszoline-C)和抗 HIV 活性 7-甲氧基-O-methylmukonal 和 clausine K(clauszoline-J)的全合成。3-甲氧基-4-甲基苯胺和环己二烯鎓铁络盐之间连续形成C-C和C-N键,得到2,7-二甲氧基-3-甲基咔唑,它是四种生物碱的常见中间体。

Using the iron-mediated arylamine cyclization as the key step we have achieved a short and highly efficient access to the biologicallyactive 2,7-dioxygenated tricyclic carbazolealkaloids 7-methoxy-O-methylmukonal, clausine H (clauszoline-C), clausine K (clauszoline-J) and clausine O.
