Effective hydrolysis of epoxides and aziridines was conducted in water at 60 or
100°C. Other types of nucleophile such as amines, sodium azide, and thiophenol
could also efficiently open epoxides and aziridines in hot water. Hot water acts
as a modest acid catalyst, reactant, and solvent in the hydrolysis reactions.

A N-heterocyclic carbene serves as an efficient catalyst for the
regioselective ring-opening reactions of aziridines in the presence of acid
anhydrides to afford the desired products in good to excellent yields.

The chemoselective ring opening of N-tosyl aziridines with aldehydes
catalyzed by an N-heterocyclic carbene gave carboxylates of 1,2-amino alcohols. A plausible mechanism for this reaction is discussed.
