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.

A short and efficient total synthesis of naturally occurring carbazole clauraila A (1) is described. The approach is designed on the basis of the key regioselective Diels-Alder reaction of the properly substituted exo-2-oxazolidinone diene 3 with acrolein (4) to give the corresponding adduct 2. The latter is converted to functionalised diarylamine 8, which is cyclised to the desired carbazole 1 through a Pd-promoted or -catalysed double C-H bond activation process in a fairly good overall yield.
