A series of aminoglycoside-capped macrocyclic structures has been prepared using intramolecular bis-tethering of neomycin on three aromatic platforms (phenanthroline, acridine, quinacridine). Based on NMR and calculations studies, it was found that the cyclic compounds adopt a highly flexible structure without conformationalrestriction of the aminoglycoside moiety.

The didemnin class of biologically active cyclodepsipeptides, isolated from a marine tunicate, has shown antitumor, antiviral, and immunosuppressive activities. Synthetic studies were undertaken to prepare a modified analog of one of the most potent congeners, didemninB (1). The side chain of the isostatine unit was tethered into the macrocycle viaa cyclohexane ring in order to provide a more rigid
