5-disubstituted tetrazoles (1,5-DTs) is presented. The strategy exploits a reductive approach to synthetize a cyclic chiral imine substrate which is then converted into the target product through an Ugi-azide three-component reaction (UA-3CR). The final products are equipped with additional functionalities which can be further elaborated for the generation of combinatorial libraries of enantiopure heterocycles
四唑已被广泛研究其生物学特性。提出了一种大规模合成1,5-二取代四唑(1,5-DTs)的有效途径。该策略采用还原性方法合成环状手性亚胺底物,然后通过Ugi-叠氮化物三组分反应(UA-3CR)将其转化为目标产物。最终产品配备了其他功能,可以进一步完善这些功能,以生成对映纯杂环的组合库。
