“…But, unfortunately, data points are not sufficient to analyze the occurrence of these catalyses quantitatively. Recently, specific base, GB, GA, and GB‐HO − catalyses have been detected kinetically in cyclization of ethyl N ‐[ o ‐( N ‐methyl‐ N ‐hydroxycarbamoyl)benzoyl]carbamate to benzo‐3‐methyl‐2,3‐oxazine‐1,4‐dione within the pH range 5.45–7.28 14.…”
