The asymmetric synthesis of six-membered cyclic sulfamides via palladium-catalyzed alkene carboamination reactions of N-homo­allylsulfamides with aryl halides is described. High levels of enantio­selectivity were obtained with a catalyst composed of Pd2dba3 and (S)-Siphos-PE.

Palladium Catalyzed

We report the ligand enabled C(sp3)–H activation/olefination of free carboxylic acids in the γ-position. Through an intramolecular Michael-addition, δ-lactones are obtained as products. Two distinct ligand classes are identified that enable the challenging palladium-catalyzed activation of free carboxylic acids in the γ-position. The developed protocol features a wide range of acid substrates and olefin reaction partners and is shown to be applicable on a preparatively useful scale. Insights into the underlying reaction mechanism obtained through kinetic studies are reported.<br>
