transition-metal-free conditions is disclosed. An N- and S-arylation sequence of o-sulfanylanilines enabled us 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.
公开了在无过渡金属的条件下由邻-硫烷基苯胺合成N-芳基吩噻嗪的有效方法。邻硫烷基苯胺的N-和S-芳基化序列使我们能够合成各种N-芳基吩噻嗪。特别是,N-芳基吩噻嗪的一锅法合成是通过容易地获得的模块,通过对芳烃中间体进行硫胺化并按照N-和S-芳基化顺序制备邻-硫烷基苯胺来完成的。
