carbene complex was combined with a free amine dehydrogenase (GkAmDH) as a co-catalyst, enabling a cascade synthetic route to directly access chiral amines from propargylethers. This process, combining an initial gold carbene catalyzed hydration of propargylethers to ketones followed by a subsequent reductive amination, produces a wide range of chiral amines in high yields and excellent enantioselectivities
封装的金卡宾复合物与作为助催化剂的游离胺脱氢酶 ( Gk AmDH) 结合,实现了从炔丙基醚直接获取手性胺的级联合成路线。该过程将最初的金卡宾催化的炔丙基醚水合为酮,然后进行还原胺化,以高产率和优异的对映选择性生产各种手性胺。
