    tricyclic nucleoside is synthesised from a bicyclic nucleoside precursor by applying a stereoselective dihydroxylation, a regioselective tosylation and an intramolecular ether formation. This tricyclic nucleoside is constructed as a conformationally locked thymidine analogue and has been analysed by X-ray crystallography. Thus, the furanose ring of this nucleoside adopts a perfect S-type conformation and

    A series of polyhydroxylated bicyclic nucleoside derivatives is approached applying stereoselective dihydroxylation reactions. Three out of four isomeric and protected products were obtained after the stereoselectivity of dihydroxylation has been completely inverted comparing a bicyclic nucleoside with a tricyclic furanose substrate. A corresponding 2′-deoxynucleoside derivative has been obtained after an optimized deoxygenation procedure.

    The ring-closing metathesis method is applied in the construction of conformationally restricted bicyclic nucleosides. From diacetone-D-glucose, the unsaturated bicyclic carbohydrate derivative 11 is efficiently obtained through two vinyl group Grignard additions, subsequent metathesis of the double bonds, and resolution of the stereochemistry by an oxidation/reduction reaction sequence. Two separate routes differing in the 3-O-protecting group are compared. Thus, an additional protecting step improves the yields significantly. Standard conversions of 11 give the bicyclic nucleoside 22 containing an olefinic moiety with a high potential for further functionalisation. As examples, two simple bicyclic ribo-nucleoside analogues 4 and 5, which are restricted to the unusual South-type conformations, are synthesised.
