    • (b) The conversion of iminohydantoins into hydantoins was accomplished by hydrolysis in harsh conditions, whereas the conversion of iminothiohydantoins into hydantoins was achieved via KMnO4 oxidation and alkaline hydrolysis. These transformations were used by Ugi and co-workers (see ref. 1 and 2) as structural proof of the Ugi-4CC adducts.
