Deprotonation of a chiral alpha-oxygenated nitrile with the base 2,2,6,6-tetramethylpiperidylmagnesium chloride, TMPMgCl, gives rise to a chiral magnesiated nitrile, and this anion has sufficient configurational stability at low temperature to allow the formation of highly enantiomerically enriched substituted nitrile products after electrophilic quench.
手性 α-氧化腈与碱 2,2,6,6-四甲基哌啶基氯化镁 TMPMgCl 的去质子化产生手性镁化腈,并且该阴离子在低温下具有足够的构型稳定性以允许形成高度对映体富集的腈亲电猝灭后的取代腈产物。
