Simply copper: Copper(II)‐promoted intra‐ and intermolecular olefin diaminations bring together two differently functionalized amines into a vicinal relationship. High diastereoselectivity was obtained with chiral alkenes and results of the asymmetric catalysis are promising.

mCPBA-mediated metal-free intramolecular aminohydroxylation and dioxygenation reactions of unfunctionalizedolefins are reported. In the presence of 1.2 equiv. of m-chlorobenzoic peracid, different N-sulfonyl 4-penten-1-amine substrates could be cyclized via epoxide intermediates, producing the corresponding 2-hydroxymethylpyrrolidine products in up to 92% yields. The reaction could be carried out
