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.

Recent Advances in the Synthesis of PS-5 and PS-6 Antibiotics and Related Carbapenem Compounds,ide-imine method, the ester enolate-imine condensation and the hydroxamate approach. Some recent examples on the construction of the bicyclic carbapenem ring system will be briefly discussed in order to illustrate new synthetic perspectives in β-lactam chemistry.
