CARBOCYCLIC DERIVATIVES AND CONJUGATED DERIVATIVES THEREOF, AND THEIR USE IN VACCINES

The invention is in the field of vaccines and relates to oligomers having a selected degree of polymerization, obtained by connecting together a number of carbocyclic repeating units, and to conjugated derivatives thereof. The oligomers and conjugated derivatives thereof of the invention also have a selected degree of acetylation. The derivatives of the invention are useful for the preparation of immunogenic compositions, e.g. in the form of a vaccine.

Synthesis and transformations of D-glucuronic and L-iduronic acid glycals

D-Glucuronic acid glycals can be efficiently synthesized from diacetone glucose or tri-O-acetyl glycal and can be transformed into D-glucuronic acid donors and acceptors in high yields. Base catalyzed epimerization of D-glucuronic acid glycals provides access to the corresponding L-iduronic acid glycals. Both D-glucuronic and L-iduronic acid glycals were transformed into glycosylating agents for use in the synthesis of glycosaminoglycan oligosaccharides.
