malonodinitrile, and alcohols has been developed, providing a direct and efficient route to a range of structurally diverse and synthetically useful 2-alkyloxy-1H-pyrrole-3-carbonitrile derivatives. The reaction involved three different bond (C–C, C–O, and C–N) formations in a single step, and its regioselectivity was depended on the structure of the α-hydroxy ketones employed. The use of easily available
已经开发了 α-羟基酮、丙二腈和醇的碱促进三组分级联反应,为一系列结构多样且合成有用的 2-烷氧基-1 H-吡咯-3-腈提供了直接有效的途径衍生品。该反应在一个步骤中涉及三种不同的键(C-C、C-O 和 C-N)的形成,其区域选择性取决于所使用的 α-羟基酮的结构。使用容易获得的起始材料、广泛的底物范围、良好的官能团耐受性、操作简单和高原子经济性是新方法的吸引人的特点。
