[reaction: see text] An efficient and cost-effective synthesis of N(alpha)-Boc2-N(beta)-Cbz-2,3-diaminopropionic acid is reported. The synthesis starts from commercially available N(alpha)-Boc-Asp(OBn)-OH and employs a Curtius rearrangement to establish the beta-nitrogen. Proper protection of the alpha-nitrogen is essential for the success of the Curtius rearrangement.
[反应:见正文]报道了Nα-Boc2-Nβ-Cbz-2,3-二氨基丙酸的高效合成方法。合成从可商购获得的Nα-Boc-Asp(OBn)-OH开始,并采用Curtius重排建立β-氮。正确保护α-氮对于Curtius重排的成功至关重要。
