Under appropriate reaction conditions, a domino hydroformylation/Wittig olefination can be accomplished with derivatives of allylamines and stabilized Wittig ylides. A further highly diastereoselective aza‐Michael reaction yields β‐proline derivatives. These are, for example, useful as building blocks for alkaloid syntheses.
在适当的反应条件下,可以用烯丙胺的衍生物和稳定的维蒂希酰化物进行多米诺加氢甲酰化/维蒂希烯化。进一步高度非对映选择性的氮杂-迈克尔反应产生β-脯氨酸衍生物。例如,它们可用作生物碱合成的基础。
