A simple and concise tandem cyclization of alkynoates with amines in the presence of tert -butyl perbenzoate (TBPB) leads to 1,2,4-trisubstituted 1 H -pyrroles. A variety of aromatic amines and aliphatic amines can be used in this approach, and a wide range of functionalized 1,2,4-trisubstituted 1 H -pyrroles are obtained in good to excellent yields. This protocol not only corresponds to the construction
                                    在过苯
甲酸叔丁酯 (
TBPB) 存在下,炔酸酯与胺的简单串联环化产生 1,2,4-三取代的 1 H-
吡咯。这种方法可以使用多种芳香胺和脂肪胺,并以良好到极好的收率获得各种官能化的 1,2,4-三取代 1 H-
吡咯。该协议不仅对应于
吡咯片段的构建,而且还提供了一种形成 C-C 和 C-N 键的新方法。
