Palladium-catalyzed heteroarylation of 1-substituted 1,2,3-triazoles with furans and thiophenes has been developed in the presence of pyridine and Ag2CO3.
在吡啶和Ag2CO3存在下,已经发展了钯催化的1-取代-1,2,3-三唑与呋喃和噻吩的杂环化反应。
Microwave assisted direct arylation of 1-benzyl-1,2,3-triazole
A new efficient pathway for synthesis of 1-benzyl-5-aryl-1,2,3-triazoles by regioselective directarylation between 1-benzyl-1,2,3-triazole and Ar-Br is developed. The microwave assisted reaction proceeded smoothly with good yield with high C5 position selectivity and a possible pathway of directarylation is discussed. This methodology provides a simple way to construct 1, 5-disubstituted 1,2,3-triazoles
Substituted 1-aralkyl-1H-v-triazoles are prepared from a suitable 1-aralkyl-1H-v-triazole by a process comprising an alkylation step and dependent on the product desired suitably followed by an oxidation step and decarboxylation step.
