A novel radical-based approach for the iron-catalyzed selective cleavage of acetal-derived alkylsilyl peroxides, followed by the formation of a carbon–carbon bond is reported. The reaction proceeds under mild reaction conditions and exhibits a broad substrate scope with respect to the acetal moiety and the carbon electrophile. Mechanistic studies suggest that the present reaction proceeds through a free-radical process involving carbon radicals generated by the homolytic cleavage of a carbon–carbon bond within the acetal moiety. A synthetic application of this method to sugar-derived alkylsilyl peroxides is also described.

An asymmetric synthesis of a 3′-deoxy-3′-18F-fluorothymidine (18F-FLT) precursor has been developed wherein the deoxysugar moiety was synthesized using a novel Ga-mediated allylation of (R)-2,3-cyclohexylideneglyceraldehyde as the key step. The synthesis deviates significantly from the previous syntheses of the 18F-FLT precursors wherein the expensive starting material, thymidine was used.
Synthesis of phosphonate analogues of 2-deoxyribose-1-phosphate
Rubira, María-José,Pérez-Pérez, María-Jesús,Balzarini, Jan,Camarasa, María-José
, p. 177 - 179 (2007/10/03)
Phosphonate derivatives of 2-deoxyribose have been synthesized for the first time, by Lewis acid-mediated reaction of glycosyl donors with diisopropylhydroxymetylphosphonate for compounds 2 or with triisopropyl phosphite for compounds 3. Although, the selectivity of the reaction was moderate, in both cases the α-glycosides were predominantly obtained.
Improved procedure for the regiospecific synthesis of 2'-deoxyribonucleosides
Baud,Chavis,Lucas,Imbach
, p. 4437 - 4440 (2007/10/02)
2'-Deoxyribonucleosides are regiospecifically synthesized in high yields by catalyzing with KI-dibenzo-18-crown-6 PTC the condensation between unprotected silylated purines and pyrimidines and the appropriate easily available 2-deoxy-ribofuranosyl or pyranosyl sugar derivatives.
