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

AuI/AuIIIcatalyticcycles can trigger three highly regioselective alkene difunctionalization processes that involve the formation of C(sp3)O, C(sp3)N, and C(sp3)C(sp2) bonds. The reaction can proceed by reductive elimination on the oxidized gold center with complete retention of the configuration or through two subsequent nucleophilic substitution reactions via an aziridine intermediate.
