Inhibition of the mycolicacid pathway has proven a viable strategy in antitubercular drug discovery. The AccA3/AccD4/FadD32/Pks13 complex of Mycobacterium tuberculosis constitutes an essential biosynthetic mechanism for mycolicacids. Small molecules targeting the thioesterase domain of Pks13 have been reported, including a benzofuran-based compound whose X-ray cocrystal structure has been very recently

very efficient methodology for the synthesis of the antibiotics carbazomycin A (1) and B (2) by oxidative coupling of cyclohexa-1,3-diene and the corresponding arylamine 10 (Scheme 5 and Schemes 7 and 9, resp.). The overall process is achieved by a consecutive Fe-induced formation of the CC and the CN bond. The major benefit of our Fe-mediated carbazole synthesis is that the coupling process is possible
