Synthesis of aminoglycoside derivatives on a Cbz-type heavy fluorous tag

Four aminoglycoside derivatives containing a 2,6-diamino-2,6-dideoxy-d-glucopyranose disaccharide structure were successfully prepared by using a Cbz-type heavy fluorous tag in a fluorous synthesis. A Cbz-type heavy fluorous tag was prepared using the hexakis(fluorous chain)-type alcohol 11, and the fluorous alcohol 11 was recovered in good yield after the synthesis of aminoglycoside derivatives.
