moieties can be synthesized by domino aziridine ring opening with o-halothiophenols followed by copper-catalyzed Goldberg coupling–cyclization with good to excellent yields. Less reactive o-chlorothiophenols are also successfully utilized for the dominoreaction to synthesize phenothiazine derivatives. This methodology is successfully applied in the synthesis of phenothiazine skeletons containing biologically
