3-triazole and isoxazole scaffolds has been prepared. The protocol utilized alkynyl substituted amines as the bifunctional linkers to combine a copper-free triazole synthesis with a hypervalent iodine-mediated isoxazole cycloaddition through a chemoselective process. This method has also been exemplified in the construction of bisfunctional-modified peptidomimetics by combining three reactions in a sequential
一种新型的双官能氮杂环 1,2,3-三唑并制备了异恶唑支架。该方案利用炔基取代的胺作为双功能连接子,通过化学选择性过程将无铜三唑合成与高价碘介导的异恶唑环加成反应结合在一起。通过在顺序程序中组合三个反应,在双功能修饰的拟肽模拟物的构建中也已举例说明了该方法。这种简单的无金属工艺可能会找到生物学应用。此外,所有化合物均按拉平斯基五定律分析,有望帮助发现药物。
