macropolylide
macropolylide
Macrolides (macrocyclic lactones) in which the macrocyclic ring contains more than one ester linkage. Macropolylides include macrodiolides, macrotriolides, macrotetrolides and macropentolides, each containing di-, tri-, tetra-, and penta- ester linkages, respectively, in one macrocyclic ring. Macrocyclic lactones containing nitrogen in their skeletons (azamacrolides and macrolide lactams) and also containing oxazole or thiazole in their skeletons are known in nature.
