  Design, synthesis and evaluation of 3-arylidene azetidin-2-ones as potential antifungal agents against Alternaria solani Sorauer

  摘要：

  A new concise and facile method was explored to synthesize a collection of new 3-arylidene azetidin-2-ones, which could be regarded as the derivatives of the hybrid scaffold of bioactive natural cinnamamide and heterocycle azetidi-2-one. The structures of the synthesized compounds were characterized by H-1, C-13 NMR, and MS; and their antifungal activity were evaluated against Alternaria solani Sorauer. These antifungal data were subjected to a quantitative structure-activity relationship (QSAR) analysis using Codessa software on the basis of the results from B3LYP/6-31G(d,p) quantum calculations. The best regressive model revealed that potentially more active compounds should have low dipole moments and Q(C-min) (minimal net atomic charge for a C atom), and high Q(O-max) (maximal net atomic charge for an O atom) and Q(N-min) (minimal net atomic charge for an N atom). The most potent compound 7k could lead to intracellular accumulation of reactive oxygen species, dissipation of mitochondrial transmembrane potential, and an autophagy-like cell death process in A. solani Sorauer. Taken together, these results laid the foundation for further design of improved crop-protection agents based on this hybrid scaffold. (C) 2017 Elsevier Ltd. All rights reserved.

  Treatment of methyl 2-(1-hydroxyalkyl)prop-2-enoates 1 with conc. HBr solution afforded methyl (Z)-2-(bromomethyl)alk-2-enoates 2, which were transformed regioselectively into N-substituted methyl (E)-2- (aminomethyl)alk-2-enoates 3 (SN2 reaction) and into N-substituted methyl 2-(1-aminoalkyl)prop-2-enoates 4(SN2′ reaction). Regiocontrol of nucleophilic attack by amine was accomplished simply by choice

  用浓溶液处理2-（1-羟烷基）丙-2-烯酸甲酯1。用HBr溶液得到（Z）-2-（溴甲基）烷-2-烯酸甲酯2，将其区域​​选择性地转化成N-取代的甲基（E）-2-（氨甲基）烷-2-烯酸酯3（S N 2反应）并进入ñ取代的甲基2-（1-氨基烷基）丙-2- enoates 4（S ñ 2'反应）。胺对亲核性攻击的区域控制仅通过选择溶剂即可完成，S N 2反应发生在MeCN和S N中。在石油醚中进行2'反应。水解和内酰胺化分别得到β-内酰胺7和8，分别在C（3）处含有外环亚烷基和亚甲基。
