tridentate ligands were employed for substantially advancing the purely chemical dynamic kinetic resolution (DKR) of unprotected racemic tailor‐made α‐amino acids (TM‐α‐AAs), enabling the first DKR of TM‐α‐AAs bearing tertiary alkyl chains as well as multiple unprotected functional groups. Owing to the operationally convenient conditions, virtually complete stereoselectivity, and full recyclability of the
使用结构简单且价格便宜的手性三齿配体,大大提高了未保护的外消旋特制α-氨基酸(TM-α-AAs)的纯化学动力学动力学分辨率(DKR),从而使TM-α-AAs轴承的首个DKR叔烷基链以及多个未保护的官能团。由于操作上的便利条件,几乎完全的立体选择性和手性来源的完全可回收性,这种方法应在制备TM-α-AA方面获得广泛的应用,尤其是大规模的应用。
