The base-catalysed cyclisation to the hydantoin of 2,2,3-trimethyl-5-phenylhydantoate (2; R1= R2= Me) is slower than that of the 2,3-dimethyl compound, even though the acceleration expected from the gem-dimethyl effect is observed for the acid-catalysed reaction.

The rate-surfactant profiles for the HO(-)- and AcO(-)-catalyzed ringclosure of two ethyl hydantoates, E2 and E3, to hydantoins with three cetyltrimethylammonium salts (CTAX, X = Br(-), Cl(-), or AcO(-)) are measured in 0.02 and 0.2 M acetate buffers 50% base with starting pH 4.65. Marked accelerations associated with large pH increases are found in 0.02 M buffered CTAOAc. Smaller accelerations and
