AbstractThe Suzuki–Miyaura coupling of cyclopropyl boronic derivatives with (het)aryl halides was evaluated as a method for parallel synthesis of sp3-enriched compound libraries. The scope and limitation of the procedure were established. It was shown that the method was applicable to a wide range of cyclopropyl trifluoroborates and (het)aryl bromides. Limitations of the method included trifluoroborates bearing
摘要环丙基硼衍生物与(杂)芳基卤化物的Suzuki-Miyaura偶联被评估为一种平行合成富含sp 3的化合物库的方法。确定了程序的范围和限制。结果表明,该方法适用于多种环丙基三氟硼酸酯和(杂)芳基溴化物。该方法的局限性包括在α位带有大取代基的三氟硼酸盐,以及带有酯部分的(杂)芳基溴化物。准备了一个由96个成员组成的库,以68%的成功率和30%的平均收益率说明了这一概念。所得产物的理化性质计算值(特别是sp 3-杂化碳原子分数F sp 3 = 0.16-0.83范围,平均0.52),以及通过实验观察到的可忽略的“ Log P漂移”效应(0.02单位)表明,该方法与铅导向的合成标准完全兼容。 图形摘要
