Asymmetric Synthesis of Cyclopropane Phosphonates as A Route To 2-Substituted Cyclopropylglycine, Antagonist of Metabotropic Receptors
摘要:
We describe two attempts to the synthesis of novel constrained L-AP4 analogs of potential antagonist activity. Although the first approach to introduce alkyl substituent on the amino acid carbon using cyclopropyl keton failed, conversion of cyclopropanecarboxylate into corresponding -ketophosphonate is promising and more general.
