A short and convenient route to the N-methyl-D-aspartate (NMDA) antagonist 2-carboxy-4-(3-phosphonopropyl)piperazine (CPP), involving selective N-4 alkylation of piperazine-2-carboxylic acid esters, is described. The method uses readily available starting materials and is suitable for multigram quantities.
描述了一条简便快捷的合成N-甲基-D-天冬氨酸(NMDA)拮抗剂2-羧基-4-(3-磷酰基丙基)哌嗪(CPP)的路线,涉及对哌嗪-2-羧酸酯进行选择性的N-4烷基化反应。该方法采用易于获得的起始原料,并适用于多克级量的合成。
