摘要
A simple and efficient method for the preparation of 5H-benzo[d]tetrazolo[5,1-b][1,3]thiazines has been developed. The transformation involved the copper(I)-catalyzed cascade bicyclization of o-alkenylphenyl isothiocyanates with sodium azide to afford corresponding products in moderate to good yields. This present strategy provides an effective way to construct small molecular N-, and S-heterocycles.
