Hydantoin nucleosides were synthesized from a protected methyl 2-deoXy-D-ribofuranoside in a Friedel-Crafts catalyzed silyl-Hilbert-Johnson reaction as modified by Vorbruggen. Atypical byproducts are accounted for by assuming the initial step being a ring opening of the sugar to give an acyclic glycos-1-yl cation.
