cyclopropane moieties were constructed through transition metal catalyzed [2 + 1]-cycloaddition of aromatic vinyl fluorides, and the absolute stereochemistry of the representative compound (-)-21a was established. Functional activity measuring calcium flux at 5-HT2 receptors reveals high potency for compounds (+)-21a-d. In particular, (+)-21b had no detectable 5-HT2B agonism and displayed reasonable selectivity
在我们先前关于2-苯基环丙基甲基胺的研究工作的基础上,设计并合成了一系列新的氟化5-HT 2C激动剂,作为治疗中枢神经系统疾病的潜在方法。通过过渡金属催化芳族氟乙烯的[2 +1]-环加成反应,构建了关键的氟化环丙烷部分,并建立了代表化合物(-)-21a的绝对立体化学。测量5-HT 2受体处钙通量的功能活性显示出对化合物(+)-21a-d的高效力。特别地,(+)-21b没有可检测的5-HT2B激动作用,并且显示出对5-HT2A的合理选择性。进一步进行了分子对接研究,以解释化合物与5-HT2C受体的可能结合姿势。
