tert‐butanesulfinyl imines, and subsequent Pauson‐Khand reaction of resulting enyne derivatives, carried out both stoichiometrically and catalytically. The Pauson‐Khand reaction tolerated both substituted alkenes and alkynes, and took place in good yields and diastereoselectivities, even when applied to a gram‐scale synthesis.
通过基于先前未描述的氟化叔丁亚砜亚胺的非对映选择性炔丙基化反应以及随后产生的烯炔衍生物的Pauson-Khand反应,采用化学计量和催化方法合成了对映体富集的氟化单萜生物碱类似物。Pauson-Khand反应可耐受取代的烯烃和炔烃,并且即使用于克级合成,也具有良好的收率和非对映选择性。
