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.

2-(2′-Hydroxyphenyl)benzoxazole (HBO) may be used as a model base pair to study solvation, duplex environment, and tautomerization within the major and minor groves of DNA duplexes. In its ground state, HBO possesses an enol moiety which may be oriented s
A mild and rapid glycosylation reaction between pyrimidine bases and 2-deoxyribofuranosyl N,N,N',N'-tetramethylphosphoroamidates

A trimethylsilyl triflate-mediated coupling reaction to produce protected 2′-deoxynucleosides has been developed by using N,N,N',N'-tetramethylphosphoroamidate as a leaving group. In this reaction, employment of a 3,4,5-trimethoxybenzoyl group as the 3-hydroxyl protective group in the sugar moiety improved the β-stereoselectivity via a novel 1,3-participation.
Stereoselective synthesis of α-linked 2-deoxysaccharides and furanosaccharides by the use of 2-deoxy 2-pyridyl-1-thio pyrano- and furanosides as donors and methyl iodide as an activator

A practical and highly stereoselective glycosidation methodology is described, where anomeric mixture of 2-deoxy 2-pyridyl-1-thiopyranoside donors (1-3,27) have been coupled with several sugar alcohols (4-8,29,31) on activation by methyl iodide to obtain axially linked 2-deoxysaccharides (9-17,30,32,33). Application of this method for the synthesis of disaccharide fragment 28 of avermectin is also described. Utility of this method is also shown by use of 2-pyridyl-1-thiofuranosides (34-36) as donors to prepare α-linked furanosides (42-51).

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.
