Synthesis of 4"-benzyloxyimino-4"-deoxyavermectin B1a derivatives
摘要:
Six new 4"-benzyloxyimino-4"-deoxyavermectin B1a derivatives were synthesized from avermectin B1a by the selective protection of C-5-hydroxy group, oxidation of C-4"-hydroxy group, and deprotection followed by reaction with O-substituted hydroxylamine hydrochlorides. Their structures were confirmed by IR, 1H NMR, 13C NMR and MS. Insecticidal activities of the derivatives against Phopalosiphum pseudobrassicae, Spodoptera exigua and Pluteua xylosteua were evaluated.
