The parallel solution-phase synthesis of a new combinatorial library of 3-[4-(R1-coumarin-3-yl)-1,3-thiazol-2-ylcarbamoyl]propanoic acid amides 9 has been developed. The synthesis involves two steps: 1) the synthesis of core building blocks - 3- [4-(coumarin-3-yl)-1,3-thiazol-2-ylcarbamoyl]propanoic acids, 6 - by the reaction of 3-(omega-bromacetyl)coumarins 1 with 3-amino(thioxo)methylcarbamoylpropanoic
开发了 3-[4-(R1-香豆素-3-基)-1,3-噻唑-2-基氨基甲酰基]丙酰胺 9 的新组合库的平行溶液相合成。合成涉及两个步骤:1) 通过 3-(欧米茄-溴乙酰基)香豆素 1 与 3-氨基(硫代)甲基氨基甲酰基丙酸(5);2)使用1,1'-羰基二咪唑作为偶联剂合成相应的3-[4-(香豆素-3-基)-1,3-噻唑-2-基-氨基甲酰基]丙酰胺9。讨论了该方法与现有方法相比的优点。
