  An improved procedure for the preparation of arylthioureas consists of the reaction of benzoyl isothiocyanate with anilines in acetone and debenzoylation of the resultant N-aryl-N′-benzoylthioureas with 5% aqueous sodium hydroxide. Bicycloalkylthioureas and N-(arylalkyl)thioureas (e.g., 9H-9-fluorenylthiourea) are directly prepared from the corresponding isothiocyanates and ammonia.

  制备芳基硫脲的改进方法包括将苯甲酰异硫氰酸酯与苯胺在丙酮中反应，然后用5%氢氧化钠水溶液对生成的N-芳基-N'-苯甲酰硫脲进行去苯甲酰化。双环烷基硫脲和N-(芳烷基)硫脲（例如9H-9-芴基硫脲）可直接由相应的异硫氰酸酯与氨反应制备。

  Es werden die Synthesen von 4.5‐Bis(4‐methoxyphenyl)‐2‐arylthio‐imidazolen, ‐thiazolen und oxazolen beschrieben und deren entzündungshemmende Eigenschaften vergleichend dargestellt. Untersucht wurden Thioether, Sulfoxide und Sulfone der Phenyl‐, Fluorphenyl‐ und 2‐Thienylderivate. Die Oxazolderivate zeigten nahezu keine entzündungshemmende Aktivität, eine mittlere Wirkstärke haben die Thiazole, am

  Quinones of Benzo- and Dibenzo-Crown Ethers: The preparation of the 1,4-quinones of benzo[15]crown-5 (1), benzo [18]crown-6 (2) and dibenzo[18]crown-6 (3) and their quinols is described. The quinones are obtained by Fremy salt oxidation of the corresponding 3-hydroxybenzo-crown ethers which are readily accessible by a double protective group synthesis from 1,2,3-trihydroxybenzene. The synthetic pathway also provides a general high yield preparation of 2,3-dialkoxyl-1,4-benzoquinones. The new crown ethers are characterised b y 1H- and 13C-N. M. R. as well as U. V. spectroscopy. Non-aqueous redox potentials are determined by cyclic voltammetry. Crystalline complexes of 1 and 2 with various ammonium, alkali, and alkaline earth cations are also described.

  3-substituted (chloro, bromo, fluoro or methyl) 7-(3,3-dimethyl-1-triazeno)-10-methylphenothiazines were synthesized as potential antitumor agents. Treatment of p-substituted anilines with ammonium thiocyanate in the presence of bromine gave 6-substituted 2-aminobenzthiazoles which, after methylation with methyl iodide were hydrolyzed in 50% potassium hydroxide to give 5-substituted 2-methylaminothiophenols

  Chloracylamido derivatives IIIa-Va were obtained by acylation of 4-amino-s-hydrindacene with chloroacetyl chloride, 2-chloropropionyl chloride and 3-chloropropionyl chloride; their reactions with excessive diethylamine, pyrrolidine, piperidine and morpholine afforded the title compounds IIIbcde-Vbcde. A reaction of 4-amino-s-hydrindacene with benzoyl isothiocyanate gave 1-benzoyl-3-(s-hydrindacen-4-yl)thiourea (VI) whose mild alkaline hydrolysis resulted in N-(s-hydrindacen-4-yl)thiourea (VII). The following treatment with methyl iodide and then with ethylenediamine afforded the imidazoline derivative VIII in a low yield. N-(s-Hydrindacen-4-yl)-2-piperidinoacetamide (IIId) in the form of the hydrochloride revealed a high degree of local anaesthetic and antiarrhythmic activity.

  通过使用氯乙酰氯、2-氯丙酰氯和3-氯丙酰氯对4-氨基-s-氢吲哚啉进行酰化反应，得到了Chloracylamido衍生物IIIa-Va；它们与过量的二乙胺、吡咯烷、哌啶和吗啡啉反应，形成了标题化合物IIIbcde-Vbcde。4-氨基-s-氢吲哚啉与苯甲酰异硫氰酸酯反应，得到1-苯甲酰-3-(s-氢吲哚啉-4-基)硫脲（VI），其轻微碱性水解产生N-(s-氢吲哚啉-4-基)硫脲（VII）。随后，使用甲基碘和乙二胺进行处理，得到了低收率的咪唑啉衍生物VIII。以盐酸形式出现的N-(s-氢吲哚啉-4-基)-2-哌啶乙酰胺（IIId）具有高度的局部麻醉和抗心律失常活性。
