Keywords: | Supercritical carbon dioxide; 1,3-Dipolar cycloaddition; Azomethine ylides; Aziridines | Issue Date: | 2006 | Citation: | Tetrahedron Letters. 47:31 (2006) 5475-5479 | Abstract: | The 1,3-dipolar cycloaddition of azomethine ylides with DMAD in supercritical carbon dioxide is reported. The photolysis reaction conditions were optimized with a suitable adjustment of pressure, temperature, irradiation time and co-solvent concentration leading to a more efficient reaction than in neat acetonitrile. Similar results were observed using thermal reaction conditions. Supercritical carbon dioxide with a minute co-solvent addition is shown to be a very efficient medium for promoting this type of cycloadditions. | URI: | https://hdl.handle.net/10316/5078 | DOI: | 10.1016/j.tetlet.2006.05.179 | Rights: | openAccess |
