Synthesis of Cyclic and Acyclic Pyrimidine Nucleosides Analogues with Anticipated Antiviral Activity
Abstract
A convenient method for preparation of cyclic and acyclic nucleosides was achieved by alkylation of 6-(2,4-dichlorophenoxymethyl)pyrimidine-2,4-dione (1) with a variety of acyclic and cyclic activated sugar analogues, namely (2-acetoxyethoxy)methyl acetate (3), 2-(acetoxymethoxy)propane-1,3-diyl dibenzoate (4), benzyloxymethyl acetate (5), 2-acetoxy-5-(benzoyloxymethyl)tetrahydrofuran-3,4-diyl dibenzoate (12), 5-chloro-2-((4-chlorobenzoyloxy)methyl)tetrahydrofuran-3-yl 4-chlorobenzoate (13) and 2-(acetoxymethyl)-6-bromotetrahydro-2H-pyran-3,4,5-triyl triacetate (14), respectively. Deprotection of the synthesized nucleosides was achieved by using methanolic ammonia. The structures of the newly synthesized nucleoside analogues were fully characterized by analytical methods (mass spectrometry, 1H NMR, 13C NMR, and elemental analysis).
