Herein, a new route toward 2,4‐substituted pyrroles is presented. This is a new, simple, fast, and convenient method furnishing 2,4‐substituted pyrroles based on the formal cycloaddition reaction of isocyanides with acyclic enamines or enaminones under basic conditions.
在此,提出了一种新的制备2,4-取代吡咯的途径。这是在异氰酸酯与无环烯胺或烯胺酮在碱性条件下正式环加成反应的基础上,提供2,4-取代吡咯的一种新的,简单,快速和方便的方法。
