with secondary amines and chloro-acid chlorides; SN2 reaction with sodium azide; and the selective [3 + 2] Hüisgen cycloaddition with appropriate terminal alkynes. The target secondary and tertiary 1,2,3-triazoloamide derivatives were obtained with three-diversity points in excellent overall yields and purities using the reported solid- and solution-phase synthetic routes, respectively.
开发了用于制备仲和叔1,2,3-三唑酰胺衍生物的有效合成途径。通过先前开发的固相合成方法构建并扩展了第二个α-1,2,3-三唑酰胺库,并通过并行溶液相合成方法构建了叔1,2,3-三唑酰胺库。合成途径依赖于与仲胺和氯酰氯形成酰胺。SN2与叠氮化钠反应;以及使用适当的末端炔烃进行的选择性[3 + 2]Hüisgen环加成反应。使用所报道的固相和溶液相合成路线,分别以优异的总收率和纯度获得具有三个多样性点的目标1,2,3-三唑酰胺二级和三级衍生物。
