A versatile method for the synthesis of chiral 1,4-disubstituted-1,2,3-triazole derivatives starting from easily accessible naturally occurring D-or L-amino acids as chiral synthons is described. The amino acids were converted into azido alcohols, followed by copper catalyzed [3+2] cycloaddition reactions between the azido alcohols and methyl propiolate and subsequent ester aminolysis with primary
描述了一种从容易获得的天然存在的 D-或 L-氨基酸作为手性合成子开始合成手性 1,4-二取代-1,2,3-三唑衍生物的通用方法。将氨基酸转化为叠氮醇,然后在铜催化下,叠氮醇与丙炔酸甲酯发生[3+2]环加成反应,随后用伯胺和仲胺进行酯氨解,得到目标化合物,收率优异,且无外消旋化。所选目标化合物的对接表明,手性1,4-二取代-1,2,3-三唑衍生物具有模仿已知嘌呤类似物的结合模式的潜力。
