参考标题:Stereoselective Lewis Acid Mediated (3+2) Cycloadditions OfN-H- AndN-Sulfonylaziridines With Heterocumulenes 作者:Robert A. Craig,Nicholas R. O'Connor,Alexander F. G. Goldberg,Brian M. Stoltz |发布日期:2014.4.14 摘要:Alkyl And Aryl Isothiocyanates And Carbodiimides Are Effective Substrates In (3+2) Cycloadditions With N‐sulfonyl‐2‐substituted Aziridines And 2‐phenylaziridine For The Synthesis Of Iminothiazolidines And Iminoimidazolidines. Additionally, The Stereoselective (3+2) Cycloaddition Of N‐h‐ And N‐sulfonylaziridines With Isothiocyanates Can Be Accomplished, Allowing For The Synthesis Of Highly Enantioenriched
