A new synthetic route to thiadiazolylaminoglycosides, by a ring expansion/ring contraction sequence of glycosyl triazines, has been developed. Two potential mechanisms of this oxidative ring contraction 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.
