A new synthesis of enantiomerically pure malonylphenylalanyl and malonylmethylphenylalanyl derivatives was developed in which the corresponding prochiral enamides were treated by asymmetric hydrogenation using the Rh(I)-(S,S)-Me-DuPHOS system. These unnatural amino acids were suitably protected and can be used in solid phase peptide synthesis.
开发了对映体纯的丙二酰基苯丙氨酰基和丙二酰基甲基苯丙氨酰基衍生物的新合成,其中使用Rh(I)-(S,S)-Me-DuPHOS系统通过不对称氢化处理了相应的手性烯酰胺。这些非天然氨基酸被适当地保护并且可以用于固相肽合成中。
