A series of unprotected pseudo-disaccharides and pseudo-trisaccharides of 2-deoxystreptamine-containing aminoglycosides have been selectively acylated at the N-1 position with the valuable (S)-4-amino-2-hydroxybutanoyl (AHB) pharmacophore by using the recombinant BtrH and BtrG enzymes from butirosin biosynthesis in combination with a synthetic acyl donor. The process was optimized by performing two
