About this book. Aziridines and epoxides are among the most widely used intermediates in organic synthesis, acting as precursors to complex molecules due to the strains incorporated in their skeletons. Besides their importance as reactive intermediates, many biologically active compounds also contain these three-membered.

Aziridine is the organic compounds consisting of the three-membered heterocycle (CH 2) 2 NH. [5] [6] It is a colorless, toxic, volatile liquid that is of significant practical interest.

[7] The class of aziridines are of broader interest in medicinal al formula: C₂H₅N. Aziridines are organic compounds containing the aziridine functional group, a three-membered heterocycle with one amine (-NR-) and two methylene bridges (-CR 2-). The parent compound is aziridine (or ethylene imine), with molecular formula C 2 H 4 l drugs feature aziridine rings, including mitomycin C, porfiromycin, and azinomycin B (carzinophilin).Beilstein Reference:   Aziridines are recognized as some of the most versatile synthetic intermediates in organic synthesis and for their importance in nitrogen-containing biologically active compounds.
