Synthesis of Theophylline and 6-Thiotheophylline 7-Ribosyl Nucleosides

The syntheses of theophylline and thiotheophylline 7-ribopyranose and 7-ribofuranose nucleosides, both by direct coupling of the base and the sugar and by construction of the imidazole ring, are reported. The conformational syn/anti equilibrium of the peracetyl derivatives was studied by molecular mechanics and by the low-temperature line-shape/1H NMR method. Wiley-VCH Verlag GmbH & Co.

Nucleoside Syntheses, XXII. Nucleoside Synthesis with Trimethylsilyl Triflate and Perchlorate as Catalysts

The novel Lewis acids (CH3)3SiOSO2CF3 (5), (CH3)3SiOSO2C4F9 (6), and (CH3)3SiClO4 (4) are highly selective and efficient Friedel-Crafts catalysts for nucleoside formation from silylated heterocycles and peracylated sugars as well as for rearrangements of persilylated protected nucleosides.With basic silylated heterocycles these new catalysts give much higher yields of the natural N-1-nucleosides than with SnCl4.
