Heteropoly acid as a novel nitrene transfer agent: a facile and practical aziridination of olefins with Chloramine-T.
Environmentally benign HPA is found to be an efficient catalyst for aziridination of olefins in the presence of inexpensive Chloramine-T as a nitrogen source: instantaneous at room temperature, requires only stoichiometric amount of olefin and no allyl amine side product.
متن کاملStereoselective aziridination of cyclic allylic alcohols using chloramine-T.
The stereoselective aziridination of a range of cyclic allylic alcohols using two different chloramine salts (4-MeC(6)H(4)SO(2)NClNa, TsNClNa and t-BuSO(2)NClNa, BusNClNa) has been explored. The stereoselectivity of these reactions was highly dependent on the structure of the allylic alcohol and the chloramine salt. Generally, mixtures of cis- and trans-hydroxy aziridines were obtained, in whic...
متن کاملIodoamidation of olefins with chloramine salts and iodine in aqueous media.
An efficient, unique, and convenient method for the iodoamidation of olefins with chloramine salts and I(2) in aqueous media is described. This method was applicable to a wide range of olefins, including aromatic, aliphatic, and electron-deficient olefins.

متن کاملNovel aziridination of olefins: direct synthesis from sulfonamides using t-BuOI.
tert-Butyl hypoiodite (t-BuOI) was found to be a powerful reagent for synthesis of aziridines from olefins and sulfonamides. The aziridination of olefins was achieved by using sulfonamides with t-BuOI. Our preliminary findings represent the example of metal-free aziridination of olefins with readily accessible sulfonamides as a nitrogen source.
