There is a broad and interesting set of synthetic methods for reaching these compounds. Aziridination represents the most explored tool, but there are several other more specific, less well-known, but highly promising approaches. Therefore, the current review focuses on recently described or updated ways to obtain 3-arylated aziridines via different non-aziridination-based synthetic methods, reported mainly since 2000. The presented methods belong to two main directions of synthesis, namely, cyclization of open-chain substrates and rearrangement of other heterocycles. Cyclization of open-chain substrates includes the classic Gabriel-Cromwell type cyclization of halogenated substrates with amines, base-promoted cyclization of activated aminoalcohols (or its analogues), and the oxidative cyclization of \u03b2-dicarbonyls. Rearrangements of other heterocycles are presented as the Baldwin rearrangement of 4-isoxazolines, the cycloaddition of 1.3-dipoles or dienes to 2H-azirines, and the addition of C- and N-nucleophiles to the double bond of azirines.<\/jats:p>","DOI":"10.3390\/ijms23115919","type":"journal-article","created":{"date-parts":[[2022,5,25]],"date-time":"2022-05-25T08:41:33Z","timestamp":1653468093000},"page":"5919","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Non-Aziridination Approaches to 3-Arylaziridine-2-carboxylic Acid Derivatives and 3-Aryl-(aziridin-2-yl)ketones"],"prefix":"10.3390","volume":"23","author":[{"given":"Boriss","family":"Strumfs","sequence":"first","affiliation":[{"name":"Latvian Institute of Organic Synthesis, 21 Aizkraukles Street, LV-1006 Riga, Latvia"},{"name":"Department of Pathology, Riga Stradins University, 16 Dzirciema Street, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kirils","family":"Velikijs","sequence":"additional","affiliation":[{"name":"Department of Pathology, Riga Stradins University, 16 Dzirciema Street, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Romans","family":"Uljanovs","sequence":"additional","affiliation":[{"name":"Department of Pathology, Riga Stradins University, 16 Dzirciema Street, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stanislavs","family":"Sinkarevs","sequence":"additional","affiliation":[{"name":"Department of Pathology, Riga Stradins University, 16 Dzirciema Street, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7393-9524","authenticated-orcid":false,"given":"Ilze","family":"Strumfa","sequence":"additional","affiliation":[{"name":"Department of Pathology, Riga Stradins University, 16 Dzirciema Street, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"599","DOI":"10.1002\/anie.199405991","article-title":"Chiral Aziridines\u2014Their Synthesis and Use in Stereoselective Transformations","volume":"33","author":"Tanner","year":"1994","journal-title":"Angew.
