Structural Modification of Macrolide Antibiotics,ssfully utilized for synthetic transformations. Even though this research effort has yielded several new derivatives which have been pursued with more intensive studies and commercial development, additional opportunities still remain for the discovery of novel structural modifications of macrolides which confer advantageous biological features.
