Five 5-benzyloxyimino-5-deoxyavermectin B1a derivatives 4a~4e were synthesized from aver- mectin B1a by selective oxidization of the hydroxyl group at C-5, followed by the reaction with O-substi- tuted hydroxylamines. Their structures were confirmed by 1H NMR, 13C NMR, IR and MS spectra. Insecticidal activities of compounds 4a~4e were tested against Helicoverpa armigera and Spodoptera exigua.

Key words: 5-benzyloxyimino-5-deoxyavermectin B1a, synthesis, O-substituted hydroxylamine, avermectin
