Look, no metal: A metal‐free catalytic procedure for aziridination of alkenes using tetrabutylammonium iodide as the catalyst, m‐chloroperoxybenzoic acid (mCPBA) as the terminal oxidant, and N‐aminophthalimide as the nitrenium precursor has been developed (see scheme; right: X‐ray structure of one of the products). Control experiments suggests that the active oxidant is in situ generated hypoiodous

specific oxidant for PhthNH2 to create a highly chemoselective aziridination reagent. This method efficiently effects aziridination of electron-rich, electron-deficient, allylic alcohol and alkenyl bromide CC bonds in good to excellent yields. Inter and intramolecular chemoselectivity was demonstrated between electron-rich and electron-deficientalkenes by using this efficient and metal free protocol.

Aryl iodide mediated aziridination of a variety of alkenes with N-aminophthalimide under mild conditions (m-CPBA, K(2)CO(3), CH(2)Cl(2), 25 degrees C) was achieved in moderate to good yields (up to 94%). By recovering the aryl iodide, a recyclable system is developed with product yield over 79% attained for the aziridination of trans-1,2-diphenylethylene.

Aziridination of a variety of alkenes with N-substituted hydrazines mediated by iodobenzene diacetate under mild conditions (K2CO3, CH2Cl2) and ambient temperature were achieved in good to excellent yields (up to 99%), and conversions. The practicality and simplicity of this C-N bond formation protocol was exemplified by its application to the aziridination of cholesteryl acetate in a stereoselective manner. (C) 2004 Elsevier Ltd.
