One-pot synthesis of tryptophanol derivative from N-Boc-aziridine and indole has been developed. The ring opening reaction of the aziridine takes place smoothly at -30°C in a regioselective manner and tolerates a wide range of functional groups including halogens attached to the aromatic ring, which was also performed on a gram scale. The resulting tryptophanol derivative was converted to (-)-indolactam V from commercially available 4-bromoindole through a copper-mediated aryl amination in nine steps with an overall yield of 32%.
