An efficient route for the asymmetric synthesis of α,α-disubstituted α-amino acids derivatives (1, 2, and 3) starting from readily available epoxy silyl ethers (6) has been developed. High enantiomeric purity can be realized by the present method using a combination of MABR rearrangement of a chiral epoxide and Curtius rearrangement.
已经开发了从容易获得的环氧甲硅烷基醚(6)开始不对称合成α,α-二取代的α-氨基酸衍生物(1、2和3)的有效途径。通过使用手性环氧化物的MABR重排和Curtius重排的组合,可以通过本发明方法实现高对映体纯度。
