a variety of ketones, β-keto esters, aldehydes, etc., during enamine–palladium catalysis. Density functional theory calculations reveal that Bz-Gly-OH assists in the formation of an enamine that attacks the π-allylpalladium complex via an outer sphere mechanism. The preliminary result points to an asymmetric allylic alkylation under a new mode of bifunctional catalysis.
在烯胺-钯催化过程中,单保护氨基酸 Bz-Gly-OH 有助于各种酮、β-酮酯、醛等的烯丙基烷基化。密度泛函理论计算表明,Bz-Gly-OH 有助于形成烯胺,该烯胺通过外球机制攻击 π-烯丙基钯络合物。初步结果表明在双功能催化新模式下的不对称烯丙基烷基化。
