Aziridine is an organic compound consisting of the three-membered heterocycle C 2 H 5 N. [ 5 ] [ 6 ] It is a colorless, toxic, volatile liquid that is of significant practical interest. [ 7 ] Aziridine was discovered in 1888 by the chemist Siegmund Gabriel . [ 8 ]
In organic chemistry, aziridines are organic compounds containing the aziridine functional group (chemical structure (R−) 4 C 2 N−R), a three-membered heterocycle with one amine (>NR) and two methylene bridges (>CR 2). [2] [3] [4] The parent compound is aziridine (or ethylene imine), with molecular formula C 2 H 4 NH.
The molecular formula C 2 H 5 N (molar mass: 43.07 g/mol, exact mass: 43.0422 u) can refer to: Aziridine; Ethanimine or its tautomer, vinylamine; N-Methylmethanimine
Aziridiniums are the ionic form of the class of molecules known as aziridines. [1] Aziridines can be used to insert nitrogen atoms during synthesis, but without any substituents attached to the nitrogen in the ring, they are considered nonactivated and inert. [2] They can be rendered active by the preparation of aziridinium ions.
Propyleneimine (or propylene imine) is the organic compound with the formula CH 3 CH(NH)CH 2. It is a secondary amine and the smallest chiral aziridine (ring containing C 2 N). It is a flammable colorless liquid. Its derivatives, copolymers and oligomers, are of commercial interest. [4]
Alternatively, they can be obtained by oxidation of the corresponding aziridine. Azirine can be generated during photolysis of isoxazole. [ 3 ] Due to the weak N-O bond, the isoxazole ring tends to collapse under UV irradiation, rearranging to azirine.
The Blum–Ittah aziridine synthesis, also known as the Blum–Ittah-Shahak aziridine synthesis [1] or simply the Blum aziridine synthesis is a name reaction of organic chemistry, for the generation of aziridines from oxiranes.
The mitomycins are a family of aziridine-containing natural products isolated from Streptomyces caespitosus or Streptomyces lavendulae. [1] [2] They include mitomycin A, mitomycin B, and mitomycin C. When the name mitomycin occurs alone, it usually refers to mitomycin C, its international nonproprietary name. Mitomycin C is used as a medicine ...
