5-依维菌素B1a酯的合成和生物活性
Synthesis and Bioactivity of 5-Ivermectin B1a Esters
【摘要】 依维菌素B1a与羧酸在DMAP/DCC体系中直接酯化 ,得到 10个 5 IVB1a酯衍生物 ,产率 6 6 %~ 82 %;它们的化学结构得到IR ,1HNMR ,13 CNMR和MS谱的确证 .它们具有良好的杀虫、杀螨活性 .
【Abstract】 Ten 5-Ivermectin B 1a ester derivatives were prepared from Ivermectin B 1a and carboxylic acids in the systems of DCC/DMAP. Their chemical structures were determined by IR, 1H NMR, 13C NMR and MS spectra. The preliminary results of bioassay showed that L-1~L-10 have good insecticidal activities.
