Highly enantioselective and facile synthesis of α-hydroxy-β-amino acids has been achieved using the Claisen and Curtius rearrangements as key reactions. Chiral allylic alcohols were employed, which can be prepared by asymmetric catalysis in both E- and Z-forms; both anti- and syn-α-hydroxy-β-amino acids have been synthesized.
使用 Claisen 和 Curtius 重排作为关键反应已经实现了 α-羟基-β-氨基酸的高度对映选择性和简便合成。采用手性烯丙醇,可通过不对称催化制备E-和Z-型;已经合成了抗和顺-α-羟基-β-氨基酸。
