A new route to aminodiazines is reported, the ortho-directed lithiation of diazines is used, followed by reaction with tosyl azide as an electrophile. The reduction of the azido or tetrazolo compounds obtained was achieved and led to the expected amines. This methodology has allowed the synthesis of new aminodiazines and an improvement in the yield of various aminodiazines previously described. This reaction was used for the preparation of an aza analogue of Nevirapine.
报道了一种合成氨基二嗪的新路线,使用了二嗪的邻位定向锂化,随后与作为电亲体的托烯基叠氮化物反应。对所获得的叠氮或四唑化合物进行了还原,得到了预期的胺。这种方法学使得新氨基二嗪的合成成为可能,并提高了之前描述的各种氨基二嗪的产率。该反应被用于制备 Nevirapine 的氮杂类似物。
