The first transannulation of 1,2,3-triazoles with terminal alkynes into pyrroles is reported. The reaction proceeds in the presence of a Rh2(oct)4/AgOCOCF3 binary catalyst system providing a straightforward approach to 1,2,4-trisubstituted pyrroles in good to excellent yields.
报道了具有末端炔烃的 1,2,3-三唑的第一次环化成吡咯。该反应在 Rh 2 (oct) 4 /AgOCOCF 3二元催化剂体系的存在下进行,提供了一种以良好到极好的产率获得 1,2,4-三取代吡咯的直接方法。
