2-Alkyl-1-allyl-3-arylsulfonyl-isothioureas III are not described in the literature. These compounds are valuable intermediate products for new potentially bioactive sulfonamide derivatives. The title compounds III can be prepared from 1-allyl-3-arylsulfonyl-thioureas I with monohalogen alkanes under alkaline conditions (method A) or from N-arylsulfonyl-iminothiocarbonic acid ester chlorides II with excess allylamine (method B).
2-烷基-1-烯丙基-3-芳基磺酰基异硫脲III在文献中未被描述。这些化合物是新的潜在生物活性磺酰胺衍生物的有价值的中间产物。标题化合物III可以从碱性条件下的1-烯丙基-3-芳基磺酰基硫脲I与单卤代烷烃制备(方法A),或从N-芳基磺酰基亚氨基甲酸酯氯化物II与过量烯丙胺制备(方法B)。
