摘要：

A new chiral auxiliary (3S)-N,N'-bis(p-methoxybenzyl)-3-isopropylpiperazine-2,5-dione 7 has been developed for the asymmetric synthesis of a-amino acids. The auxiliary 7 employs a novel chiral relay network based on non-stereogenic N-benzyl protecting groups which enhance the diastereoselectivity observed during alkylation of its C-6 enolate 25.
