Drug-lead synthesis through rapid construction of chiral molecular complexity around the biologically relevant framework using a highly efficient strategy is a key goal of organic synthesis. Molecules bearing a spirooxindole-type framework exhibit important bioactivities. Herein, we present a highly efficient and convenient strategy that allows rapid construction of unique optically active spiro[oxazoline-3
通过使用高效策略围绕生物相关框架快速构建手性分子复杂性,药物先导合成是有机合成的一个关键目标。带有螺环吲哚型骨架的分子表现出重要的生物活性。在此,我们提出了一种高效便捷的策略,通过羟醛反应通过有机催化不对称合成螺环硫代氨基甲酸酯,可以快速构建独特的旋光性螺[恶唑啉-3,3'-羟吲哚]。使用急性神经炎症模型对几种螺恶唑啉进行的初步生物学评估显示出有希望的解热活性,并为发现新的解热剂提供了机会。
