reacting 2-alkylthiohydantoins (IIla) and (XII), respectively, with morpholine and/or piperidine. Moreover, treating of two equivalents of XIVa-d with one equivalent of piperazine afforded 1,4[di-(5-phenylmethylene-hydantoinyl)]-piperazines (XVIa,b). The behaviour of 2-alkylthiohydantoins towards alanine and anthranilic acid was also investigated. The structure of the products was established by correct
摘要 2-硫代乙内酰脲衍生物与作为重氮甲烷的重氮烷反应。研究了二苯基重氮甲烷和/或9-重氮芴。通过 2-硫代乙内酰脲 (Ia,b) 和 (X) 与重氮甲烷的反应制备了几种 2-硫代乙内酰脲 (IIa,b)、(IIIa,b)、(XI) 和 (XII)。2-吗啉-和/或2-哌啶基-糖脒(VIIa,b)和(XVa,b)分别通过使2-烷硫基乙内酰脲(IIla)和(XII)与吗啉和/或哌啶反应来制备。此外,用一当量的哌嗪处理两当量的 XIVa-d 得到 1,4[二-(5-苯基亚甲基-乙内酰脲基)]-哌嗪 (XVIa,b)。还研究了 2-烷硫基乙内酰脲对丙氨酸和邻氨基苯甲酸的行为。
