Hitting the right target: Differentiation between two keto moieties was accomplished by a regio‐ and enantioselective bioamination employing ω‐transaminases. Using 1,5‐diketones as substrates gave access to the optically pure 2,6‐disubstituted piperidine scaffold. The approach allowed the shortest synthesis of the alkaloid dihydropinidine, as well as its enantiomer, by choosing an appropriate ω‐transaminase
达到正确的目标:通过使用ω-转氨酶进行区域和对映选择性生物胺化,可实现两个酮基部分的区分。使用1,5-二酮作为底物可以进入光学纯的2,6-二取代的哌啶骨架。通过选择合适的ω-转氨酶,该方法可以最短地合成生物碱二氢吡啶及其对映体。
