Diverse substituted pyridines and pyrimidines with high selectivity were obtained using a concise and efficient protocol developed herein. The reaction proceeds via metal-free cascade annulation of isopropene derivatives. Using isopropene derivatives as C3 synthons, NH4I as the “N” source, and formaldehyde or dimethyl sulfoxide as the carbon source, this reaction realizes the efficient formation of
使用本文开发的简洁有效的方案获得了具有高选择性的多种取代的吡啶和嘧啶。该反应通过异丙烯衍生物的无金属级联环化进行。该反应以异丙烯衍生物为C3合成子,NH 4 I为“N”源,甲醛或二甲亚砜为碳源,实现了分子间C-N和C-C键的高效形成。
