Abstract
There are disclosed novel compounds which are derived from 22,23-dihydro avermectin B1 aglycone. The compounds are both isomers of the 27-hydroxy adduct of the substrate avermectin compound that have been glycosylated at the 4' position to yield 4'-O-glucosyl 27-OH avermectin compounds. The compounds and the intermediates used to make them are highly potent antiparasitic, insecticidal and anthelmintic avermectin agents.
