A radical solution: A highly regioselective copper(II)‐catalyzed oxyamination of N‐acyl indoles with oxaziridines gave aminal products that could be converted in a single step into 3‐aminoindoles and 3‐aminopyrroloindolines (see scheme). When a chiral N‐acyl group was used, the core fragment of some architecturally fascinating pyrroloindoline alkaloids was formed with 91 % ee. Bs=benzenesulfonyl, Moc=methoxycarbonyl
