Intramolecular C-Arylation of Benzylated Sugars. The Unexpected Double C-Glycosideration of Tris-O-m-methoxybenzyl-β-D-ribofuranose Derivatives

Article abstract of DOI:10.1039/c39860000497

Upon treatment with tin(IV) chloride, D-ribofuranose derivatives bearing activated O-benzyl groups were found to undergo single or double intramolecular C-arylation, with m-methyl- and m-methoxy-substituted benzyl groups respectively.
