C=C bonds of enimines (α,β-unsaturated imines). Preliminary studies suggest their hydrolysed ring-open ω-amino enones are the likely substrates for this step. When combined with imine reductase (IRED)-mediated C=N reduction, the result is an efficient telescoped sequence for the preparation of diastereomerically enriched 2-substituted saturated amine heterocycles.
烯还原酶 (ERED) 催化缺电子 C=C 键的还原。在这里,我们报告了 ERED 催化的亚胺(α,β-不饱和亚胺)的 C=C 键的净还原的第一个例子。初步研究表明,它们水解的开环 ω-氨基烯酮可能是该步骤的底物。当与亚胺还原酶 (IRED) 介导的 C=N 还原结合时,结果是用于制备非对映异构富集的 2-取代饱和胺杂环的有效伸缩序列。
