Combining three bioactive units, such as 2(5H)-furanone, 1,2,3-triazole, and amino acid together into one potential drug molecule with polyfunctional groups, a series of new chiral 2(5H)-furanone derivatives containing 1,2,3-triazole moiety have been designed and synthesized from (5S)-5-alkoxy-3,4-dibromo-2(5H)-furanones, amino acids, propargyl bromide, and organic azides via the sequential three steps
将三个生物活性单元(例如2(5 H)-呋喃酮,1,2,3-三唑和氨基酸)结合到一个具有多官能团的潜在药物分子中,一系列新的手性2(5 H)-呋喃酮衍生物由(5 S)-5-烷氧基-3,4-二溴2(5 H)-呋喃酮,氨基酸,炔丙基溴和有机叠氮化物通过依次的3个设计并合成了1,2,3-三唑部分步骤,包括非对称迈克尔加成-消除,取代和点击反应。后两个步骤(替换和点击反应)可以在一锅过程中顺利进行。此外,目标产物可以通过四组分一锅法直接合成。
