Catalytic hydrogenolysis of the Z‐isomer of a series of aryl‐substituted ketene heterodimers facilitated access to deoxypropionate derivatives, favoring the anti‐isomer, and with excellent transfer of chirality. Anti‐β‐elimination and an anti‐selective hydrogenation of an E‐olefin intermediate are proposed to be key steps.
一系列芳基取代的乙烯酮异二聚体的Z-异构体的催化氢解作用有利于获得脱氧丙酸酯衍生物,有利于抗异构体,并具有出色的手性转移能力。反-β-消除和抗一的-选择性加氢Ë烯烃中间提出是关键步骤。
