The synthesis of (2S)- and (2R)-2-(3'-phosphonobicyclo[1.1.1]pentyl)glycine isomers (10 and 11), characterized by the bioisosteric replacement of the distal carboxylic group of 2-(3'-carboxybicyclo[1.1.1]pent-1-yl)glycine by the phosphonate moiety, was accomplished by a stereoselective Ugi condensation. The two isomers were tested for their activity against an array of metabotropic glutamate receptors
(2S)-和(2R)-2-(3'-膦酰基双环[1.1.1]戊基)甘氨酸异构体(10和11)的合成,其特征在于2-(3'通过立体选择性Ugi缩合完成膦酸酯部分的-羧基双环[1.1.1]戊-1-基)甘氨酸。测试了这两种异构体对一系列代谢型谷氨酸受体的活性,结果发现S异构体(10)是一种中等效力和选择性的mGluR4激动剂。
