By using Rh–H catalysis, we couple α‐nitroesters and alkynes to prepare α‐amino‐acid precursors. This atom‐economical strategy generates two contiguous stereocenters, with high enantio‐ and diastereocontrol. In this transformation, the alkyne undergoes isomerization to generate a RhIII–π‐allyl electrophile, which is trapped by an α‐nitroester nucleophile. A subsequent reduction with In powder transforms
通过使用 Rh-H 催化,我们将 α-硝基酯和炔烃偶联以制备 α-氨基酸前体。这种原子经济策略产生两个连续的立体中心,具有高对映和非对映控制。在这种转化过程中,炔烃经过异构化生成 Rh III -π-烯丙基亲电子试剂,该亲电子试剂被 α-硝基酯亲核试剂捕获。随后用 In 粉末还原将烯丙基 α-硝基酯转化为相应的 α,α-二取代 α-氨基酯。
