activated alkene bonds by ene‐reductases (ERs) is completely chemoselective, because of the mechanism of the reaction. Thus, we investigated the use of ERs belonging to the Old Yellow Enzyme family for the reduction of α,β‐unsaturated aldehydes with a conjugated C≡C triple bond at the γ position. This reaction was exploited as the key step for the development of an effective homologation route to convert
在炔烃的存在下烯烃的化学选择氢化是用传统化学方法实现的非常具有挑战性的转化。开发一种有效的方法来进行这种转化将丰富有机化学家可用的工具包,以开发有用的合成路线,并创建新的结构基序。由于反应机理,烯还原酶(ER)还原活化的烯烃键是完全化学选择性的。因此,我们研究了使用旧黄色酶家族的ER来还原在γ位上具有共轭C≡C三键的α,β-不饱和醛。
