An effective method for highly enantioselective alkynylation of ketoimine (alpha-trifluoromethyl ketoimine ester) has been developed via a zinc/BINOL catalyzed process. This protocol provides a useful and facile access to optically active quaternary alpha-trifluoromethyl alpha-amino acids and related derivatives of interest in life sciences.
通过锌/ BINOL催化的方法,开发了一种高效的对映体选择性催化酮亚胺(α-三氟甲基酮亚胺酯)炔化方法。该协议为生命科学中感兴趣的旋光性α-三氟甲基α-氨基酸和相关衍生物提供了有用且便捷的途径。
