Matsuzawa, Tsubasa published the artcileSynthesis of diverse phenothiazines by direct thioamination of arynes with S-(o-bromoaryl)-S-methylsulfilimines and subsequent intramolecular Buchwald-Hartwig amination, Recommanded Product: 2-Bromo-5-methoxybenzene boronic acid, the publication is Chemistry Letters (2018), 47(7), 825-828, database is CAplus.
A facile method for the synthesis of diverse phenothiazines was achieved by direct thioamination of aryne intermediates with S-(o-bromoaryl)-S-methylsulfilimines and subsequent intramol. Buchwald-Hartwig amination. Since various sulfilimines were prepared easily by odorless copper-catalyzed ipso-thiolation of readily available o-bromoarylboronic acids followed by imination and hydrolysis, this approach enabled the synthesis of a wide variety of multisubstituted phenothiazines.
