Hydrogen‐bond mediated coupling of 1,2,3‐triazoles to indoles and pyrroles results in N2 selective functionalization of the triazole moiety in moderate to excellent yields. The reaction was tolerant of un‐, mono‐ and disubstituted triazoles and was applied to synthesize tryptophan derived fluorescent amino acids.
氢键介导的1,2,3-三唑与吲哚和吡咯的偶合导致三唑部分的N2选择性官能化,产率中等至优异。该反应可耐受未取代,单取代和双取代的三唑,可用于合成色氨酸衍生的荧光氨基酸。
