[Method] With nonanoic acid and vanillin as starting materials, nonivamide was prepared by reductive amination and N-acylation reaction, and the chemical structure of target compound was confirmed by 1H NMR and EI-MS. The biological activities of nonivamide and capsaicin were tested. [ Result] Both capsaicin and synthetic nonivamide had no obvious insecticidal activities against third instar larvae of diamondback moth [ Plutella xyllostella （Linnaeus） ] and 3-day-old nymphs of broad bean aphids （Aphis craccivora）. [ Conclusion] The research provided theoretical basis for further study on insecticidal activities of capsaicin.展开更多
With maleic acid as the raw material, 6-methyl-4-hydroxy-2-pyrone, 6-methyl-4-alkoxy-2-pyrone and 6-methyl-4-hydroxy-3-acyl-2-pyrone derivatives were obtained via loop closing, O-alkylation and acylation reaction, and...With maleic acid as the raw material, 6-methyl-4-hydroxy-2-pyrone, 6-methyl-4-alkoxy-2-pyrone and 6-methyl-4-hydroxy-3-acyl-2-pyrone derivatives were obtained via loop closing, O-alkylation and acylation reaction, and antifungal activity was also tested. Structure of products was characterized by 1H NMR and MS, and preliminary biological activity tests showed that some of this series of compounds had good inhibitory activity against Rhizoctonia solani and Fusarium mo- niliforme Sheld.展开更多
