Regio‐ and stereoselective oxyamination of dienes through a tandem rhodium‐catalysed aziridination–nucleophilic opening affords racemic oxazolidinone derivatives, which undergo a kinetic resolution acylation process with amidine‐based catalysts (ABCs) to achieve s values of up to 117. This protocol was applied to the enantioselective synthesis of sphingosine.
通过串联铑催化的叠氮化-亲核开口进行二烯的区域和立体选择性氧化胺化反应,得到外消旋的恶唑烷酮衍生物,其与with基催化剂(ABCs)进行动力学拆分酰化反应,可得到高达117的s值。采用了该协议对鞘氨醇的对映选择性合成。
