  Synthesis of Functionalized Pyrrolizidines/Pyrrolidines Incorporating a Spirooxindole Motif through [3+2] Cycloaddition

  摘要：

  Dimethyl 2-(aryloxy)fumarates and dimethyl 2-(alkyl- or arylthio)fumarates are shown to be efficient dipolarophiles in 1,3-dipolar cycloaddition reaction with azomethine ylides, which are generated by the reaction of isatin with the secondary amino acids proline or sarcosine. In these reactions, dimethyl 2-(alkyl- or arylthio)fumarates afforded spirooxindolopyrrolizidines or -pyrrolidines in high yields with excellent regioselectivities, while dimethyl 2-(aryloxy)fumarates produced mixtures of regioisomers. DFT calculations at the B3LYP/6-31G(d,p) level were consistent with the observed results. Tri- and tetracyclic compounds were obtained through regio- and stereoselective intramolecular cycloaddition of O-vinylic salicylaldehyde with secondary amino acids.

  The stereoselective formation of C–O, C–S and C–N bonds by the reaction of phenols, thiols and amines with activated alkynes is described. The reactions are successfully conducted in water with excellent yields at room temperature. The lack of organic solvent use in the work-up procedure, the short reaction time and the environmentally benign mild reaction conditions are advantages of this method.

  通过酚、硫醇和胺与活化炔烃的反应，实现了C−O、C−S和C−N键的选择性立体形成。这些反应在室温下水相中以优异的产率成功进行。该方法的优势在于后处理过程中无需使用有机溶剂、反应时间短以及温和的环境友好型反应条件。
