New phosphorylating reagents 1 and 2 were prepared in three steps from 4-hydroxybenzaldehyde. They showed good efficiency in the solid phase synthesis of 5′-phosphate monoester nucleosides. End-phosphate DNA sequence synthesis demonstrated the efficiency of the new reagents (1 and 2) according to the general procedure of automated DNA synthesis. The oxidation of P(III) to P(V) and the removal of benzyl...
The reactivity in water of a series of nucleosides and nucleotides towards ferrocenemethanol was investigated. Several adducts incorporating the ferrocenemethyl moiety into the heterocyclic base were isolated and their activity was tested against HIV-1, HBV, YFV, BVDV and several bacteria. However, none of the new compounds showed significant antiviral activity nor cytotoxicity. The reaction with...
