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.

A cheap, easy‐to‐execute and sustainable synthetic methodology for the synthesis of indoles and benzofurans was developed utilizing Pd/C as the promoter. A great variety of substituted ortho‐allyl anilines or phenols were utilized, leading to products in moderate yields. Recycling of the catalyst up to five times has been achieved.

A concise method for the synthesis of cyclic sulfamides and vicinaldiamines is presented. This method is enabled by Cu(OAc)2 and demonstrates a new transformation for this metal. Both five- and six-membered vicinal diamine-containing heterocycles have been synthesized in good to excellent yields, and substrate-based asymmetric induction has been achieved. This is the first reported example of intramolecular

methyleneoxy-functionalized dihydroindolines and pyrrolidines. Tetramethylaminopyridyl radical (TEMPO) serves as both the source of the oxygen and the stoichiometric oxidant. These reactions are catalyzed by copper(II) triflate, complexed with (4S,5R)-Bis-Phbox. The unprotected aminoalcohols can be obtained by sequential dissolving metal reductions of the N-S and O-N bonds.
本文报道了铜催化的烯烃的对映选择性分子内氨基氧化。这是对映选择性分子内烯烃氨基氧化过程的第一份报告。N-Arylsulfonyl-2-allylanilines 和 4-pentenylarylsulfonamides 以高产率和良好的对映选择性环化,提供新的手性亚甲氧基官能化二氢二氢吲哚和吡咯烷。四甲基氨基吡啶基(TEMPO)既是氧源又是化学计量氧化剂。这些反应由与 (4S,5R)-Bis-Phbox 络合的三氟甲磺酸铜 (II) 催化。未保护的氨基醇可以通过连续溶解 NS 和 ON 键的金属还原来获得。
