Racemic synthesis of novel 2′,5′,5′-trifluoro-apiose nucleoside phosphonic acid analogs were performed as potent antiviral agents. Phosphonation was performed by direct displacement of triflate intermediate with diethyl (lithiodifluoromethyl) phosphonate
Efficient electrophilic fluorination for the synthesis of novel 2'-fluoro-3'-methyl-5'-deoxyphosphonic acid apiosyl nucleoside analogues

Novel 5'-deoxyapiosyl purine phosphonic acid analogues with a 2'-electropositive moiety, such as, a fluorine atom were designed and synthesized from commercially available hydroxylacetone. Condensation of a glycosyl donor 10 with purines under Vorbruggen conditions and cross-metathesis give the desired nucleoside phosphonic acid analogues 14, 17, 21, and 24. The synthesized nucleoside analogues were subjected to antiviral screening against HIV-1, and the adenine analogue 17 exhibited weak in vitro anti-HIV-1 activity (EC50 = 26.6 μM)

Abstract: The presilylation of purine and pyrimidine nucleobases as well as other related N-heterocycles with HMDS utilizing chitosan–silica sulfate nanohybrid (CSSNH) is described. CSSNH is proved to be a useful, highly efficient and eco-friendly heterogeneous nanohybrid catalyst for silylation of nucleobases. The presilylated nucleobases then underwent the reaction with different sources of carbon electrophiles to afford the desired N-alkyl-substituted derivatives in good-to-excellent yields. CSSNH exhibits several advantageous involving ease of handling and preparation, low cost, reusability and environmental benignity. These unique properties render the CSSNH to be an ideal candidate for use in green industrial processes. Graphic abstract: [Figure not available: see fulltext.].

The preparation of 2′-deoxy-2′-siprodifluorocyclopropany-lnucleoside analogs has been achieved from α-d-glucose in several steps. The key step in the synthesis was the introduction of the difluorocyclopropane through a difluorocarbene type reaction at the 2′-position. Then, a series of novel 2′-deoxy-2′-spirodifluorocyclopropanyl nucleoside analogs were synthesized using the Vorbrüggen method. All the synthesized nucleosides were characterized and subsequently evaluated against hepatitis C and influenza A virus strains in vitro.
