An efficient catalytic aminohydroxylation reaction of alkenes in aqueous media is disclosed for the first time. The multiple roles water plays as a reactionmedium, nucleophile, and Brønsted acid catalyst provide high reactivity and chemo- and regioselectivities to this transformation. This method provides easy access to various valuable vicinal amino alcohols in a sustainable manner.

A copper-catalyzed aziridination of aliphatic alkenes promoted by N-heterocyclic carbene ligands is described. The readily available catalyst IPrCu(DBM) can catalyze aziridination of a variety of aliphatic alkenes using alkenes as the limiting reagents.
