A novel, efficient method has been developed for the synthesis of propargylamines through a three-component coupling of aryl azides, aldehydes, and alkynes in the presence of iron–iodine–copper(I) bromide as catalyst. This method is the first example for directly using aryl azides as an amino component in a three-component coupling reaction. Some of the major advantages of this protocol are: good yields

An efficient methodology has been developed for the synthesis of both di- and trisubstituted thiazol-2(3H)-ones from N-propargylamines and silver(I) trifluoromethanethiolate (AgSCF3) in good yields. The reaction proceeds via [3,3]-sigmatropic rearrangement/5-exo-dig cyclization of N-propargylamines. The starting material can be easily prepared from the A3-coupling reaction of amines, aldehydes, and
已经开发出一种有效的方法,用于从N-炔丙基胺和三氟甲硫醇银 (I) (AgSCF 3 ) 以良好的收率合成二取代和三取代的 thiazol-2(3 H )-ones。该反应通过N-炔丙基胺的 [3,3]-σ 重排/5- exo -dig 环化进行。起始材料可以很容易地由胺、醛和炔烃的 A 3 -偶联反应制备。该方法可以扩展到噻唑-2(3 H )-硫酮衍生物的合成,并对一些合成化合物的光物理性质进行了研究。

2,4-Disubstituted quinoline derivatives were obtained from N-aryl-2-propynylamines catalyzed by copper(I) and gold(I) complexes. The quinoline derivatives could also be obtained by the reaction of N-arylaldimines with terminal acetylenes via the formation of N-aryl-2-propynylamines.
