practical strategy for ceric ammonium nitrate promoted highly chemo- and regioselective ortho-nitration of aniline carbamates has been developed under mild and neutral conditions without the requirement of additional catalyst and oxidant. Both electron rich and highly electron-deficient anilines afforded good to excellent yields of the desired products with outstanding functional groups tolerance.
在温和和中性条件下,无需额外的催化剂和氧化剂,开发了一种新的实用的硝酸铈铵促进苯胺氨基甲酸酯的高度化学和区域选择性邻位硝化的策略。富电子苯胺和高度缺电子苯胺均能以优异的收率获得所需产品,并具有出色的官能团耐受性。
