1. Studies on nucleoside H-phosphonoselenoate chemistry and chalcogen exchange reaction between P(V) and P(III) compounds
Abstract : In this thesis, the chemistry of compounds containing P-Se bonds has been studied. As a new addition to this class of compounds, H-phosphonoselenoate monoesters, have been introduced and two synthetic pathways for their preparation have been developed. READ MORE

2. Studies on the synthesis of nucleotide analogues containing P-F and P-Se bonds
Abstract : In the present work, new synthetic approaches to the synthesis of nucleoside phosphorofluoridate and phosphorofluoridothioate diesters have been developed. These procedures involve either oxidative transformation of the corresponding H-phosphonate or H-phosphonothioate diesters in the presence of fluoride anion or iodine-promoted desulfurization of phosphorothioate or phosphorodithioate diesters in the presence of fluoride anion.
