, p. 7961 - 7964 (1995)
The anti-AIDS drug AZT is prepared in six steps in 44percent overall yield starting from the readily available ribonucleoside 5-methyluridine.

, p. 735 - 737 (2002)
The reaction of 5′-O-benzoyl-2,3′-anhydrothymidine with dimethylammonium azide in the system DMF-1,4-dioxane in the temperature range from 80 to 100°C follows the overall second-order kinetics and first-order kinetics with respect to each reactant. The activation parameters in the systems containing 30, 40, and 50 vol % of dioxane are, respectively: ΔH298≠ 99, 85, and 79 kJ/mol; ΔS 298≠ -46, -83, and -101 J mol-1 K -1. A refined model of the transition state for the rate-determining stage was proposed, which takes into account specific interaction with 1,4-dioxane.
Mechanisms of 5'-O-benzoyl-2,3'-anhydrothymidine reactions with nucleophiles: II. Kinetics of azidation with dimethylammonium azide in DMF-dioxane

, p. 1369 - 1372 (2007/10/03)
The reaction of 5'-O-benzoyl-2,3'-anhydrothymidine with dimethylammonium azide in the system DMF-1,4-dioxane at 100°C follows the overall second-order kinetics or first-order in each of the reactants. Raising the dioxane fraction from 0 to 50 vol % accelerates the process due to low polarity of the transition state in the rate-determining stage.
