Abstract
Benzyl 2,5-di-O-(tert-bstvldimethvl)silvl-3-O-triflvl-β-D-ribofsranoside (13) underwent triflyl migration upon O-desilylation with triethylammonium hydrogen fluoride in tetrahydrofuran affording benzyl 2-O-triflyl-β-D-ribo-furanoside (7) in ca. 5% yield, together with three other products, benzyl 3-O-triflyl-β-D-ribofuranoside (17), benzyl 2-O-(tert-butyldimethyl)silvl-3-O-triflyl-β-D-ribo-furanoside (18) and benzyl 3-deoxy-β-D-glvceropento-furanos-2-uloside (16). In order to confirm the triflyl migration, a series of reactions were performed.Keywords
