Synthesis and Biological Activity of 4a,4"-Disubstituted Avermectins
摘要:
Allylic oxidation of avermectin B-1 and C-4''-substituted avermectin B-1 analogues at C-4a followed by derivatization of the C-4a oxygen provides compounds that have an improved safety profile, as judged by mouse LD(50) data, and are substantially more potent than avermectin B-1 against flies.
