Ten kinds of N-substituted-2-(2-aminoethyl)thiopseudoureas (AETs) were prepared. 1'-Phenyl-AET (VI) gave 2-aminothiazoline derivative (XXIII) with one equivalent of alkali, while other AETs having at least one hydrogen atom at the amino nitrogen underwent intramolecular rearrangement to give MEGs. GEDs were prepared from these MEGs by mild oxidation. The NMR and IR spectra of these compounds were also discussed.
制备了十种 N-取代的-2-(2-氨基乙基)硫代假脲类化合物(AET)。1'-Phenyl-AET (VI) 与一个当量的碱反应生成 2-氨基噻唑啉衍生物 (XXIII),而其他在氨基氮上至少有一个氢原子的 AET 则发生分子内重排反应生成 MEG。用这些 MEG 通过温和氧化制备出 GED。此外,还讨论了这些化合物的核磁共振和红外光谱。
