依维菌素B_(1a)与羧酸在DMAP/DCC体系中直接酯化，得到10个5-IV B_(1a)酯 衍生物，产率66%～82%；它们的化学结构得到IR，~1H NMR, ~(13)c nmr和MS谱的 确证。它们具有良好的杀虫、杀螨活性。

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, ~(13)C NMR and MS spectra. The preliminary results of bioassay showed that L-1～L- 10 have good insecticidal activities.
