Matsuzawa, Tsubasa published the artcileTransition-Metal-Free Synthesis of N-Arylphenothiazines through an N- and S-Arylation Sequence, Computed Properties of 89694-44-0, the publication is Organic Letters (2021), 23(6), 2347-2352, database is CAplus and MEDLINE.
An efficient synthetic method of N-arylphenothiazines, e.g., I, from o-sulfanylanilines under transition-metal-free conditions is disclosed. An N- and S-arylation sequence of o-sulfanylanilines enabled the authors to synthesize a wide variety of N-arylphenothiazines. In particular, one-pot synthesis of N-arylphenothiazines was accomplished from easily available modules through preparation of o-sulfanylanilines by thioamination of aryne intermediates and following N- and S-arylation sequence.
