Synthesis of anhydro psicofuranosyl nucleosides

Methyl 1-O-mesyl-5-O-toluoyl-β-D-psicofuranoside (5) was synthesised from the known 1,3;4,5-di-O-isopropylidene-β-D-psicofuranose (1) as a key carbohydrate precursor for the preparation of anhydro psicofuranosyl nucleosides. Transformation of 5 into aceta
