Short and sweet: A general strategy for the synthesis of ten disaccharide aminoglycosides, including three natural trehalosamines, neotrehalosyl 3,3′‐diamine, and six synthetic aminoglycosides, is developed. The aminoglycoside compounds have different anomeric configurations and numbers of amino groups. Glycosylation coupling of a stereodirecting donor with a configuration‐stable TMS glycoside acceptor

dynamics that was enabled by trehalose-fluorophore conjugates capable of labeling trehalose glycolipids in live actinomycetes. We identified fluorescein-trehalose analogues that are metabolically incorporated into the trehalose mycolates of representative Mycobacterium, Corynebacterium, Nocardia, and Rhodococcus species. Using these probes, we studied the mobilities of labeled glycolipids by time-lapse
