regioselective, efficient and convenient synthesis of 2-aminobenzophenones through acylation of anilines with α-oxocarboxylic acids assisted by tert-butyl nitrite is presented. Interestingly, tert-butyl nitrite acts as not only an efficient and mild nitrosation reagent, but also a sustainable oxidant required in the Pd(II)-catalyzed decarboxylative acylation. Meanwhile, the NO unit turned out to be
本文提出了亚硝酸叔丁酯辅助下的α-氧代羧酸酰化苯胺,对苯胺进行区域选择性,高效,便捷的合成。有趣的是,亚硝酸叔丁酯不仅充当有效且温和的亚硝化试剂,而且还充当Pd(II)催化的脱羧酰化反应所需的可持续氧化剂。同时,发现NO单元是用于区域选择性酰化的易于引入且易于除去的导向基团。
