Nitrile oxides reacted with sulfonyl isothiocyanates to give 3-substituted-5-sulfonylimino-1,4,2-oxathiazoles (4a-i) in moderate to good yields. Although thermolysis of the adducts at ca. 200° furnished a complex mixture of reaction products, decomposition in methanol or dimethylamine proceeded cleanly and yielded respectively urethanes and ureas.
腈氧化物与磺酰基异硫氰酸酯反应,以中等至良好的收率得到3-取代的5-磺酰亚胺基-1,4,2-氧杂噻唑(4a-i)。尽管加成物在约70℃下热解。200°提供反应产物的复杂混合物,在甲醇或二甲胺中的分解清晰进行,分别得到氨基甲酸酯和脲。
