molecules by incorporating a key enzymatic step into the synthesis. Herein, we describe a general biocatalytic approach for the enantioselective preparation of 2,6-disubstituted piperidines starting from easily accessible pro-chiral ketoenones. The strategy represents a new biocatalytic disconnection, which relies on an ω-TA-mediated aza-Michael reaction. Significantly, we show that the reversible enzymatic
不断扩大的生物催化剂“工具箱”为重新设计靶向分子的合成策略开辟了新的机会,通过将关键的酶促步骤纳入合成。在此,我们描述了一种通用的生物催化方法,用于从容易获得的前手性酮烯酮开始对映选择性制备 2,6-二取代哌啶。该策略代表了一种新的生物催化断开,它依赖于 ω-TA 介导的 aza-Michael 反应。重要的是,我们表明可逆的酶促过程可以推动胺官能团在分子框架中的穿梭,从而提供获得所需的 aza-Michael 产品的途径。
