Aziridines in Click Chemistry

Two methods that are particularly convenient for large-scale synthesis of aziridines are discussed below. Both utilize readily available chloramine salts, such as chloramine-T, as sources of nitrogen. The first method involves direct olefin azir-idination catalyzed by phenyltrimethylammonium tribromide (PhNMe3+Br3 PTAB) [42]. In the second method, 1,2-hydroxysulfonamides, conveniently obtained by osmium-catalyzed aminohydroxylation of olefins, are converted into aziridines by one-pot cyclodehydration. [Pg.455]
