N-aryl-N-[1-furyl(thienyl)but-3-enyl]amines (homoallylamines) or 2-(N-arylmethylamino)-2-furyl(thienyl)acetonitriles (α-aminonitriles) were easily prepared in good to excellent yields by an indium-mediated Barbier-type reaction between N-hetarylaldimines and allyl bromide in MeOH or a direct three component reaction between anilines, hetaryl aldehydes and trimethylsilyl cyanide in the presence of a catalytic amount
新的N-芳基-N- [1-呋喃基(噻吩基)丁-3-基]胺(高烯丙基胺)或2-(N-芳基甲基氨基)-2-呋喃基(噻吩基)乙腈(α-氨基腈)易于制备在室温下,在催化量的分子碘存在下,N-杂芳基亚胺与烯丙基溴之间的铟介导的Barbier型反应或在甲醇中存在催化量的分子碘的情况下,苯胺,杂芳基醛和三甲基甲硅烷基氰化物之间的直接三组分反应,可产生优异至优异的收率,分别。通过IR,1 H和13 C NMR光谱对整套胺进行表征。
