  Rearrangement of 2-Aryl-3,3-dichloroazetidines:  Intermediacy of 2-Azetines

  摘要：

  An easy synthesis of 2-aryl-3,3-dichloroazetidines, a rather unexplored class of azaheterocycles, is described. The title compounds were easily obtained by reduction of the corresponding 4-aryl-3,3dichloro-2-azetidinones with monochloroalane, which in turn were synthesized by a ketene-imine [2 + 2] cycloaddition. The reactivity of 3,3-dichloroazetidines with bases was investigated, yielding 2-[dimethoxy(aryl)methyl]aziridines by ring contraction when treated with sodium methoxide. Furthermore, reacting the 3,3-dichloroazetidines with sodium hydride in DMSO, followed by aqueous workup, afforded 1-alkyl-2-aroylaziridines, by hydrolysis of the intermediate 2-azetines and ring closure of the transient 3-amino-2-chloro-1-phenyl-1-propanone derivatives. Monitoring this reaction in an NMR tube, using sodium hydride in DMSO-d(6),, allowed the characterization of the intermediate strained heterocyclic enamines, i.e., 2-azetines, by H-1 and C-13 NMR.

  A straightforward synthesis of new cis-4-aryl-3-chloro-2-azetidinones was developed, using a halogen-lithium exchange reaction on 4-aryl-3,3-dichloro-2-azetidinones. This methodology was further extended to the use of alkyl halides as electrophiles, while more complex electrophiles could not be introduced.

  使用 4-aryl-3,3-dichloro-2-azetidinones 上的卤素-锂交换反应，开发了一种直接合成新的 cis-4-aryl-3-chloro-2-azetidinones 的方法。该方法进一步扩展到使用烷基卤化物作为亲电体，而无法引入更复杂的亲电体。

  Natural and synthetic β-lactam derivatives constitute an interesting class of compounds due to their diverse biological activity. Mostly used as antibiotics, they were also found to have antitubercular, anticancer and antidiabetic activities, among others. In this investigation, six new 3,3-dichloro-β-lactams prepared in a previous work were evaluated for their hemolytic and cytotoxic properties. The results showed that the proposed compounds have non-hemolytic properties and exhibited an interesting cytotoxic activity toward squamous cell carcinoma (A431 cell line), which was highly dependent on the structure and concentration of these β-lactams. Among the molecules tested, 2b was the most cytotoxic, with the lowest IC50 values (30–47 µg/mL) and a promising selectivity against the tumor cells compared with non-tumoral cells.

  天然和合成的 β-内酰胺衍生物具有多种生物活性，是一类有趣的化合物。它们大多被用作抗生素，还被发现具有抗结核、抗癌和抗糖尿病等活性。在这项研究中，我们对之前工作中制备的六种新的 3,3-二氯-β-内酰胺进行了溶血和细胞毒性评估。结果表明，所提出的化合物具有非溶血特性，并对鳞状细胞癌（A431 细胞系）表现出有趣的细胞毒性活性，这种活性与这些 β-内酰胺的结构和浓度密切相关。在测试的分子中，2b 的细胞毒性最强，IC50 值最低（30-47 µg/mL），与非肿瘤细胞相比，它对肿瘤细胞具有良好的选择性。
