Abstract

Carbohydrate derivatives of the antibiotic substance milbemycin, also identified as B-41, and of 13-hydroxy milbemycin are prepared. The carbohydrate groups are attached to the available hydroxy groups of milbemycin and to the hydroxy group synthesized at the 13-position. The reactions may be made selectively such that more than one carbohydrate group may be attached to a single position, or that multiple carbohydrate groups may be attached at different positions on the molecule. The described carbohydrate derivatives have antiparasitic activity.
