Naturally occurring 16-membered macrolides milbemycins A3 and A4 were selectively esterified at their 5-OH group with phthalic and glutaric anhydrides. The obtained monoesters were further functionalized by amide formation. Propargylamide derivatives were demonstrated to undergo 1,2,3-triazole formation upon treatment with organic azides in the presence of copper catalyst. Some of the synthesized compounds exhibited useful levels of antibacterial properties against Staphylococcus aureus and Staphylococcus epidermidis.
