Preparation of novel heterocyclic-ring analogues of BIOLF-62 : application of 29SI NMR nucleosides and the investigation of 2,4-dinitrobenzenesulfenyl as a protecting group for ribonucleotide synthesis

Boisvert, Suzanne, 1955- January 1986 (has links)
In light of the remarkable antiviral activity of acyclic nucleoside analogues such as that of BIOLF-62 against the herpes viruses, a number of products in which heterocyclic bases were coupled to the active acyclic sugar moiety were prepared and submitted for biological testing. / Various dimethoxytritylated and t -butyldimethylsilylated derivatives of arabinoadenosine were prepared and fully characterised by $ sp1$H and $ sp{13}$C NMR spectroscopy. $ sp{29}$Si INEPT as well as $ sp{29}$Si-$ sp1{ rm H}$ correlated NMR were used to study various t -butyldimethylsilyl and triisopropylsilyl substituted ribonucleosides. / In an effort aimed at the development of new and better nucleoside protecting functions, the 2,4-dinitrobenzenesulfenyl group which is stable to both acidic and basic conditions, was used for $5 sp prime$-hydroxyl protection of ribonucleosides and its compatibility with the phosphodichoridite nucleoside coupling procedure was investigated. The nitrobenzenesulfenyl group was used in conjunction with the dimethoxytrityl group for $2 sp prime$-hydroxyl protection in the synthesis of a UpU dimer. The latter was fully characterised by enzymatic degradation and HPLC analysis of the products.
