An approach to the parallel synthesis of hydantoin libraries by reaction of in situ generated 2,2,2-trifluoroethylcarbamates and α-amino esters was developed. To demonstrate utility of the method, a library of 1158 hydantoins designed according to the lead-likeness criteria (MW 200–350, cLogP 1–3) was prepared. The success rate of the method was analyzed as a function of physicochemical parameters

Potent and reversible: Dithiobisacetamides were determined to be urease inhibitors that function through a mechanism of mixed inhibition. They showed excellent potency against Helicobacter pylori urease and good antibacterial activity with nearly no cytotoxicity. The impressive biological profile of d8 (shown) underscores its suitability for further development as a therapeutic agent to tackle infections

4-Difluoroaniline (I) is a convenient initial reagent for the synthesis of many biologically active compounds [1, 2]. In continuing our investigation into the biological activity of alkenylarylamines, we have synthesized a series of aminoacetic acid difluoroanilides and analogous derivatives of 2-cyclopentenyl-4,5-difluoroaniline and studied their localanesthetic properties. The interaction of difluoroaniline I
3,4-二氟苯胺 (I) 是一种方便的初始试剂,可用于合成许多生物活性化合物 [1, 2]。在继续研究烯基芳胺的生物活性的过程中,我们合成了一系列氨基乙酸二氟苯胺和 2-环戊烯基-4,5-二氟苯胺的类似衍生物,并研究了它们的局部麻醉特性。二氟苯胺 I 与氯乙酰氯的相互作用导致氯乙酸二氟苯胺 (II)。二氟苯胺 I 的环戊烯基化并形成芳香核是通过 [3] 中描述的方法实现的,涉及胺的相互作用!与 1-氯-2-环戊烯。确定在所研究的条件下该反应的主要产物是以 60% 的产率获得的 2-环戊烯基 4,5-二氟苯胺 (III)。此外,反应混合物含有少量 (1.9%) 2-环戊烯基-3,4-二氟苯胺 (IV)。化合物IIl和IV的结构是在1R和~H NMR数据以及元素分析结果的基础上明确确定的。红外光谱显示了 NH2 基团在 3500 cm ~ [4] 区域的特征吸收带。化合物 III 的 1H NMR
