2-Sulfanylethanol was added to readily available 1-alkyl 3,5-diallyl isocyanurates to obtain 1-alkyl 3,5-bis[3-(2-hydroxyethylsulfanyl)propyl] isocyanurates. Treatment of the products with thionyl chloride gave 1-alkyl 3,5-bis[3-(2-chloroethylsulfanyl)propyl] isocyanurates whose reaction with thiourea followed by hydrolysis resulted in preparation 1-alkyl 3,5-bis[3-(2-sulfanylethylsulfanyl)propyl] isocyanurates. Oxiative cyclization of the latter gave macrocyclic disulfides in 56–75% yields. The composition and structure of the macrocyclic disulfides were established on the basis of the elemental and X-ray diffraction analyses, 1H and 13C NMR and IR spectra, as well as MALDI-TOF and electron impact mass spectra.
将 2-硫代乙醇加入到容易获得的 1-烷基 3,5-二烯丙基异氰尿酸盐中,得到 1-烷基 3,5-双[3-(2-羟乙基硫)丙基]异氰尿酸盐。将这些产物与亚硫酰氯处理后,可得到 1-烷基 3,5-双[3-(2-氯乙基硫)丙基]异氰尿酸盐,与硫脲反应后水解,可制备 1-烷基 3,5-双[3-(2-硫乙基硫)丙基]异氰尿酸盐。后者的有氧环化产生了大环二硫化物,产率为 56-75%。根据元素和 X 射线衍射分析、1H 和 13C NMR 和 IR 光谱以及 MALDI-TOF 和电子碰撞质谱,确定了大环二硫化物的组成和结构。
