摘要

利用手性二茂铁亚硒烯基阳离子对烯酸、烯醇和烯烃氨基甲酸进行不对称的分子内硒环化反应,分别得到相应的内酯、环醚和氮杂环化合物,产率中等,具有很高的非对映选择性。

Highly selective asymmetric intramolecular selenocyclisation
Asymmetric intramolecular selenocyclisation of alkenoic acids, alkenols and olefinic urethanes using chiral ferrocenylselenenyl cations proceeds smoothly to give the corresponding lactones, cyclic ethers and nitrogen-heterocyclic compounds, respectively, in moderate yields with very high diastereoselectivities.
