A Convenient Synthesis of (±)-2-Carboxy-4-(3-phosphonopropyl)piperazine (CPP)

Abstract
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.
