Two bis-C-aminoglycosyl arenes containing the angolosamine and the vancosamine moieties, which are potentially useful as the D-ring fragments of the pluramycin-type antibiotics, were efficiently synthesized by the O→C-glycoside rearrangement based strategy.
s: An efficient method for bis-C-glycosylation of resorcinol derivatives was developed by utilizing the O→C-glycoside rearrangement, where each of the two phenols serves as the pivot for selective and high-yield installation of two same or different sugar moieties.
