磺酰叠氮和炔参与的铜催化多组分反应成为近年来有机化学研究的热点.磺酰叠氮和炔在铜催化下生成的N-磺酰基烯酮亚胺中间体,可以被胺、醇和水等各类亲核试剂捕捉,也可以和各种类型的烯烃发生[2+2]、[3+2]和[4+2]等环加成反应.N-磺酰基烯酮亚胺中间体受到来自双官能团底物的分子内基团进攻以及随后发生的(环)重排和σ键迁移,更是成为构建结构丰富的具有生理和药物活性(杂)环类化合物的重要手段.主要对该领域近年来的最新研究成果进行了综述.
Copper-catalyzed multicomponent reactions involving sulfonyl azides and alkynes have become hot topics in organic chemistry.In recent years, sulfonyl azides and alkynes have been synthesized by copper catalyzed N-sulfonyl enoneimine intermediates, Alcohol, water and other nucleophiles to capture, but also with various types of olefins occur [2 +2], [3 +2] and [4 +2] and other cycloaddition reaction N-sulfonyl enone imine Intermediates are attacked by intramolecular groups from bifunctional substrates and subsequently undergo (ring) rearrangements and sigma bond transmutations, making them an important means of constructing structurally rich, physiologically and pharmaceutically active (hetero) cyclic compounds. The main research achievements in recent years in this area are summarized.
