S-Allyl N-acylmonothiocarbamates react in boiling benzene with primary and secondary amines in the presence of catalytic amounts of triethylamine. In this reaction, the S-allyl group is replaced with the amino group under formation of N-acylurea derivatives in 45 - 90% yields. The wide applicability of the reaction is demonstrated by the synthesis of eighty four N-acyl-N'-substituted and N-acyl-N',N'-disubstituted ureas with various aliphatic, aromatic and heterocyclo substituents.
S-烯丙基N-酰基单硫代氨基甲酸酯在沸腾的苯中与一次和二次胺在三乙胺的催化下反应。在这个反应中,烯丙基基团被氨基取代,形成45-90%产率的N-酰基脲衍生物。该反应的广泛适用性通过合成八十四种具有各种脂肪族、芳香族和杂环取代基的N-酰基-N'-取代和N-酰基-N',N'-二取代脲得到了展示。
