yclopropane-1-carboxylic acid (FAP4) were synthesized via diastereoselective Rh(II)-catalysed cyclopropanation of a phosphonylated fluoroalkene. Different isomers of FAP4 and the corresponding non-fluorinated analogs showed a similar pharmacological profile against the isoforms of metabotropic glutamate receptor (mGluR). Within the fluorinated series, (−)-(Z)-FAP4 and (−)-(E)-FAP4 demonstrated the
通过非对映选择性Rh(II)催化的膦酰基化氟代烯烃的环丙烷化反应合成了1-氨基-2-氟-2-(膦酰基甲基)环丙烷-1-羧酸(FAP4)的四种立体异构体。FAP4的不同异构体和相应的非氟化类似物针对代谢型谷氨酸受体(mGluR)的同工型显示出相似的药理特性。在氟化系列中,(-)-(Z)-FAP4和(-)-(E)-FAP4对mGlu4表现出最高的激动剂活性(EC 50 0.10μM )。我们的结果表明,具有氨基酸功能的氟环丙烷可能适合开发有效的构象受限的mGluR激动剂。
