Organocatalytic click! Recent advances in the metal-free enamine/enolate-mediated azide-carbonyl [3+2] cycloaddition reaction are discussed. These approaches require neither a metal catalyst nor alkyne substrates. Owing to the ready availability of carbonyl compounds, these methods thus offer excellent alternatives for the synthesis of 1,4-/1,5-disubstituted and 1,4,5-trisubstituted 1,2,3-triazoles.
有机催化点击反应!讨论了无金属烯胺/烯醇盐介导的叠氮羰基[3+2]环加成反应的最新进展。这些方法既不需要金属催化剂也不需要炔烃底物。由于羰基化合物的易得性,这些方法为合成 1,4-/1,5-取代和 1,4,5-三取代 1,2,3-三唑提供了极好的替代方法。
