Conveniently protected neamineanalogues were synthesized with a free 2′-OH group for further functionalization. An approach was investigated involving a stereoselective α-glycosidation reaction of 3,4-O-dimethoxybutanediyl-2-O-silyl protected thiomannosides with a 2-deoxystreptamine derivative. Subsequent 2-O-deprotection followed by anoxidation–reduction sequence led to α-glucosides withstereoinversion
