The allylation of benzol[e][1,2,3]oxathiazine-2,2-dioxides with allyl bromides promoted by tin powder was explored. The results showed that the allylation proceeded smoothly with high yields for a variety of substrates. When various allyl bromides were used to perform the reaction, the γ-addition products were obtained. These allylated products underwent N-allylation reaction in the presence of base, and the diallylated products of benzol[e][1,2,3]oxathiazine-2,2-dioxides were obtained in high yields. The diallylated products of benzol[e][1,2,3] oxathiazine-2,2-dioxides further underwent ring closing metathesis reaction, and the cyclic derivatives of benzol[e][1,2,3] oxathiazine-2,2-dioxides were obtained in good yield.

Key words: tin powder, allyl bromides, benzol[e][1,2,3]oxathiazine-2,2-dioxides, allylation
