M. Kataoka et al., Ethyl(methyl)dioxirane as an efficient reagent for the oxidation of nucleoside phosphites into phosphates under nonbasic anhydrous conditions, ORG LETT, 3(6), 2001, pp. 815-818
[GRAPHICS]
A convenient method for the oxidation of nucleoside phosphites into phospha
tes under nonbasic and nonaqueous conditions using commercially available e
thyl(methyl)dioxirane has been developed. This oxidation is effective with
both N-protected and N-unprotected strategies.
