one equivalent of 2,4,6‐trichloro‐1,3,5‐triazine (cyanuric chloride) generates an easy handling formylating agent for the efficient formylation of these classes of compounds to give the corresponding aldehydes under mild reaction conditions. This procedure was highly efficient, and a range of formylated indoles and pyrroles were obtained in good to excellent yields.
这项研究介绍了一种有效的方法,分别在C(3)和C(2)的位置对
吲哚和
吡咯进行选择性甲酰化。三当量的N,N-二甲基甲酰胺和一当量的2,4,6-三
氯-
1,3,5-三嗪(
氰尿酰
氯)的混合物可生成易于处理的甲酰化剂,以有效地将此类化合物甲酰化为在温和的反应条件下得到相应的醛。该方法是高效的,并且以良好至优异的产率获得了一系列甲酰化的
吲哚和
吡咯。
