摘要 天然单萜类化合物具有急性毒性和驱虫、拒食、繁殖抑制和杀虫作用。目前的工作旨在通过聚合物负载的香芹酚阴离子与烷基卤化物和酰氯反应,分别得到香芹丙烯醚和酯,使用聚合物负载反应衍生出各种醚和酯化合物。此外,对不同溶剂和载体效果的特别研究表明,Amberlite IRA 400(氯化物形式)是溶剂中最好的聚合物载体和丙酮。

abundant and potent natural products having a broad spectrum of biological activity against various pests are terpenoids, especially monoterpenoids. The chemical modification of naturalmonoterpenoids has been reported to result in modified biological activity. The present work emphasizes the structural modification of carvacrol, a phenolic monoterpenoid, through the synthesis of different ether and
12 are herein the first reported). Our research is also the first comprehensive study of carvacryl esters antifungal and of medium/long chain fatty acidesters antibacterial activities. Interesting result is that all the synthesized esters, regardless the nature of the R residue, have shown activity on fungal strain Aspergilus niger and on yeast Candida albicans comparable to carvacrol.

Cl3CCONH(2)/PPh(3) was a versatile reagent to convert carboxylic acids into their corresponding acid chlorides. This intermediate was clearly confirmed by spectroscopic methods (IR, (1)H, (13)C NMR). This one-pot reaction of in situ acid chloride generated with various alcohols successfully furnished the corresponding esters in moderate to excellent yields.
