In control: The first asymmetric total synthesis of (+)‐itomanallene A (revised structure) has been accomplished starting from commercially available (S)‐glycidol in a substrate‐controlled fashion. The approach yields α,α′‐cis‐ or α,α′‐trans‐tetrahydrofuran isomers by intramolecular alkylation with either an amide enolate or a nitrile anion, respectively.
对照:(+)-itomanallene A(修饰结构)的第一个不对称全合成已从可商购获得的(S)-缩水甘油以受底物控制的方式开始。该方法通过分别与酰胺烯酸酯或腈阴离子进行分子内烷基化反应,生成α,α'-顺式或α,α'-反式-四氢呋喃异构体。
