Three-membered rings
The three-membered ring heterocycles containing single atoms of nitrogen, oxygen, and sulfur aziridine, oxirane or (epoxides- most commonly encountered three-membered heterocycles), and thiirane respectively and their derivatives can all be prepared by nucleophilic reactions. Thus, aziridine is formed by heating β-aminoethyl hydrogen sulfate with a base (in this case Y is -OSO3H). Epoxides are easily prepared by reaction of alkenes with peracids, usually with good stereospecificity. Addition reactions proceeding by electrophilic or nucleophilic opening of the ring constitute the most generally used reactions.
