A new synthetic route to thiadiazolylaminoglycosides, by a ring expansion/ringcontraction sequence of glycosyl triazines, has been developed. Two potential mechanisms of this oxidative ringcontraction using [TBA‐Ox] are discussed. The more plausible involves formation of an oxatriazepane intermediate followed by loss of formic acid, ring opening, and subsequent recyclization.
