These derivatives might be divided into four main classes depending on the size of the heterocyclic ring i.e., oxiranes (e.g., 1), oxetanes (e.g., 2), THF derivatives (e.g., 3), and THP derivatives (e.g., 4; Fig. 1.). The latter are very rare and only limited examples can be found in lite

Although there is a plethora of synthetic methods for the formation of a C-C bond in saccharides, those which are the most frequently employed are the aldol-type condensation processes, and utili

Many unnatural, synthetically modified, unsaturated sugar derivatives posses significant biological activity. The 2,3-unsaturated nucleosides are among the most striking examples of such compounds; the most representative

Kritisches Gutachten und Berichterstattung, book [.] contains an informative survey of developments in this area. The rearrangement reactions described here are classified into five groups: double bond shifts, cyclo-rearrangements associating with double bond, rearrangements associating with epoxy system, ring isomerizations (contraction and

Carbohydrates can thus be transformed into versatile chiral starting materials having a suitable
