  Synthesis of 3-acetoxyazetidin-2-ones and 3-hydroxyazetidin-2-ones with antifungal and antibacterial activity

  摘要：

  The synthesis of a series of 3-acetoxyazetidin-2-ones 3a-n and 3-hydroxyazetidin-2-ones 6a-j is reported together with the antibacterial and antifungal evaluation of these compounds. An additional series of 3-acetoxyazetidin-2-ones 11a-h which possess a free carboxylic acid group on the N-1 aryl ring were obtained by treatment of suitably substituted Schiff bases 10a-h with acetoxyacetyl chloride. The novel bicyclic structures 7 acetoxy-6-phenyl-5-thia-1-azabicyclo[4.2.0]octan-8-one 13 and 7-hydroxy-6-phenyl-5-thia-1-azabicyclo[4.2.0]octan-8-one 14 were also obtained. Many of the compounds displayed antifungal activity in vitro when evaluated against the pathogenic fungi Cryptococcus neoformans, Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata, and Trichosporon cutaneum, while 3-acetoxyazetidin-2-ones 11a-h containing a free carboxylic acid group on the N-1 aryl ring displayed antibacterial activity against Staphylococcus aureus, Proteus vulgaris, Pseudomonas aeruginosa, Bacillus subtilis, Klebsiella aerogenes and Escherischia coli.

  氢键和甲亚胺基团取向对苄叉苯胺化合物液晶性能的影响

  摘要：

  这项研究研究了取代基和氢键，亚胺键的取向对亚苄基苯胺化合物作为液晶的行为的影响。通过苯胺及其取代的衍生物与4-甲酰基苯甲酸反应，合成了化合物4-羧基亚苄基-4-X-苯胺（X = H，F，Cl，Br，CH 3，OCH 3）1a-6a。苯甲醛及其取代的衍生物与4-氨基苯甲酸的无水乙醇反应，合成了化合物4-X-亚苄基-4-羧基苯胺（X = H，F，Cl，Br，CH 3，OCH 3）1b-6b作为溶剂。通过FT IR和1 H NMR光谱对合成的化合物进行表征，使用差示扫描量热法（DSC）和偏振光学显微镜（POM）技术研究液晶性能。根据介晶性质，已证明化合物2b-4b是双晶的，具有近晶相和向列相，化合物5b，6b是单晶的，具有向列相，而化合物1a-6a和1b没有显示出中间相。对于化合物1a – 6a的氢键结合和亚胺键的反转（与化合物1b – 6b相比）导致其介晶特性不存在。
