摘要
A convenient synthetic pathway to 2-aryl-5,6-dihydro-4H-benzo[f][1,2,4]triazolo[1,5-a]azepine derivatives 7 was developed.The synthesis was based on the cycloaddition of the 1,2,3,4-tetrahydronaphthalene α-acetoxy azo compounds 3 with Ar-CN in the presence of AlCl3 and the consecutive ring enlargement.
