3R)-1-Aminocyclopentane-1,3-dicarboxylic acid (ACPD), a potent agonist of metabotropic glutamate receptors, was synthesized from L-serine. The chiral quaternary center was constructed by C-H insertion of the alkylidenecarbene, this being generated by the reaction between lithiotrimethylsilyldiazomethane and the corresponding ketone.
从L-丝氨酸合成了(1S,3R)-1-氨基环戊烷-1,3-二羧酸(ACPD),它是代谢型谷氨酸受体的有效激动剂。通过亚烷基卡宾的CH插入来构建手性季中心,这是由硫代三甲基甲硅烷基重氮甲烷与相应的酮之间的反应产生的。
