Preparation of Aromatic and Heterocyclic Amines by the Electrophilic Amination of Functionalized Diorganozincs with Polyfunctional <i>O</i>-2,6-Dichlorobenzoyl Hydroxylamines
catalyst-free electrophilicamination, which enables the synthesis of aromatic and heterocyclic amines. By subjecting diarylzinc or diheteroarylzinc compounds to readily accessible O-2,6-dichlorobenzoyl hydroxylamines in the presence of MgCl2 in dioxane at a temperature of 60 °C (8–16 h). This new electrophilicamination allowed an expedited synthesis of two pharmaceutically significant compounds: vortioxetine
我们报告了一种无催化剂的亲电胺化,可以合成芳香胺和杂环胺。在 MgCl 2存在下,在二恶烷中,在 60 °C 的温度下,将二芳基锌或二杂芳基锌化合物与容易获得的O -2,6-二氯苯甲酰羟胺反应(8-16 小时)。这种新的亲电胺化可以加速合成两种具有药学意义的化合物:沃替西汀是德拉马尼的关键中间体。这种方法为制药行业中胺基分子的简化合成提供了机会。
