stereoselective reactions. The chemical structures of these compounds were confirmed by ¹H-NMR, ¹³C-NMR and IR spectroscopy and their physico-chemical properties were characterized. The two new series of diastereomeric compounds were tested for their local anesthetic activity and parabolic relationship between the local anesthetic activity and lipophilicity was found for both cis- and trans-series.
通过立体选择性反应合成了两个同源系列的外消旋非对映体顺式和反式(2-二甲氨基甲基环庚基)-2-烷氧基苯基氨基甲酸酯,烷基链长度范围为C 1 至C 8 。这些化合物的化学结构经 1 H-NMR、 13 C-NMR 和红外光谱证实,并对其理化性质进行了表征。测试了这两个新系列的非对映体化合物的局部麻醉活性,并发现了顺式和反式系列的局部麻醉剂活性和亲脂性之间的抛物线关系。有趣的是,顺式立体异构体表现出更高的局部麻醉活性。
