    (2-羟乙基)脲衍生物(Ia-e)在酸的存在下与亚硝酸钠反应,或在氯仿中与亚硝基氯反应,得到了3-亚硝基-2-噁唑烷酮(IIa-e),产率为10-77%。这些3-亚硝基-2-噁唑烷酮在甲醇中与氯化氢脱亚硝,得到相应的2-噁唑烷酮(IIIa-e),产率为35-60%。一种N,N-二取代脲,即1-(2-羟乙基)-1-甲基脲(If)在相同条件下也环化,生成3-甲基-2-噁唑烷酮(IIf)。文中讨论了这种环化反应的机制。

  • 4,5-Dihydroxyimidazolidin-2-ones in α-ureidoalkylation of N-carboxy-, N-hydroxy-, and N-aminoalkylureas 2. α-Ureidoalkylation of N-(hydroxyalkyl)ureas

    The α-ureidoalkylation of N-(hydroxyalkyl)ureas (ureido alcohols) with 1,3-H2- and 1,3-Me2-4,5-dihydroxyimidazolidin-2-ones was systematically studied. The yields of glycolurils decrease both in going from 1,3-H2- to 1,3-Me2-4,5-dihydroxyimidazolidin-2-one and with increasing length (or with branching) of the hydroxyalkyl chain in ureido alcohols. The optimal reaction time for ureido alcohols is 1 h. The X-ray diffraction study showed that 2-(2-hydroxy-1,1-dimethylethyl)glycoluril crystallizes as a conglomerate. The enantiomeric analysis of 2-(2-hydroxyethyl)glycoluril was carried out by chiral-phase HPLC.
    系统研究了 N-(羟基烷基)脲(脲醇)与 1,3-H2- 和 1,3-Me2-4,5- 二羟基咪唑烷-2-酮的 α-ureido 烷基化反应。从 1,3-H2- 到 1,3-Me2-4,5-二羟基咪唑烷-2-酮的过程中,以及随着脲基乙醇中羟基烷基链长度(或分支)的增加,糖醛酸的产量都会降低。X 射线衍射研究表明,2-(2-羟基-1,1-二甲基乙基)甘氨酰脲结晶为团聚体。采用手性相高效液相色谱法对 2-(2-羟乙基)甘氨酰脲进行了对映体分析。

    New (1R(*),5S(*))-2-R-2,4,6,8-tetraazabicyclo[3.3.0]octane-3.7-diones containing the terminal carboxy or hydroxy group in the substituent R were synthesized by cyclocondensation of 4,5-dihydroxyimidazolidin-2-one with 1-R-ureas. Single-crystal X-ray diffraction analysis showed that 2-carboxyethyl-2,4,6,8-tetraazabicyclo[3.3.0] octane-3,7-dione crystallizes as a racemate.
  • Discovery of a potent, low-absorbable sodium-dependent glucose cotransporter 1 (SGLT1) inhibitor (TP0438836) for the treatment of type 2 diabetes

    The design and synthesis of a novel class of low-absorbable SGLT1 inhibitors are described. To achieve low absorption in the new series, we performed an optimization study based on a strategy to increase TPSA. Fortunately, the optimization of an aglycon moiety and a side chain of the distal aglycon moiety led to the identification of compound 30b as a potent and low-absorbable SGLT1 inhibitor. Compound 30b showed a desirable PK profile in Sprague-Dawley (SD) rats and a favorable glucose-lowering effect in diabetic rats.

    Two methods for the synthesis of previously unavailable 1-substituted semithioglycolurils were developed. These methods consist of the cyclocondensation of 1-substituted ureas with 4,5-dihydroxy- or 4,5-dimethoxyimidazolidine-2-thione or glyoxal, followed by the reaction of the resulting 1-substituted 4,5-dihydroxyimidazolidine-2-ones with HSCN in a two-step one-pot procedure. Two of the desired semithioglycolurils
