A highly efficient and stereoselective synthesis of enantioenriched imidazolidines by rhodium-catalyzed intermolecular [3 + 2] cycloaddition reaction of chiral vinyl aziridines and oxime ethers has been successfully developed. Notably, both aldoximes and ketoximes are suitable substrates to afford the corresponding chiral imidazolidines in high yields with good stereoselectivity. This transformation
通过铑催化的手性乙烯基氮丙啶和肟醚的分子间[3 + 2]环加成反应,已成功开发了对映体富集的咪唑烷的高效立体选择性合成。值得注意的是,醛肟和酮肟都是合适的底物,以高收率和良好的立体选择性提供相应的手性咪唑烷。这种转化代表了一个空前的例子,该例子在乙烯基氮丙啶的环加成中利用酮亚胺衍生物作为氮杂[2C]组分。
