A novel strategy for constructing sulfur containing bis-S-heterocyclic compounds from oxime esters/vinyl azide, phenylacetylene/aldehydes and elemental sulfur (S8) has been developed. These transformations show good functional group tolerance. Various bis-S-heterocyclic products were efficiently synthesized from easily prepared or widely commercially available starting materials. In this protocol, S8 successfully served as a two-sulfur atom donor for thiophene and thiazole rings, respectively.
一种从肟酯/乙烯基叠氮化物、苯乙炔/醛和单质硫(S8)构建含硫双杂环化合物的新策略已经被开发出来。这些转化反应具有良好的官能团容忍性。各种双杂环产物可以从易于制备或广泛市售的起始原料高效合成。在本方案中,S8 成功地分别作为噻吩和噻唑环的两个硫原子供体。
