Palladium-catalyzed reaction of N-arylsulfonyl-1-alkyl-3,4-dienylamines with an aryl iodide in the presence of potassium carbonate in DMF at around 70°C affords most predominantly the 2,4-cis-disubstituted azacyclobutanes bearing an aryl group on the double bond in good yields.
N-芳基磺酰基-1-烷基-3,4-二烯基胺在碳酸钾存在下于70°C在碳酸钾存在下钯催化的芳基碘化物反应,最主要得到带有芳基的2,4-顺式-二取代的氮杂环丁烷基团在双键上的产率很高。
