An operationally green, electron‐catalyzed, photochemical tandem carbodifluoroalkylation/radical cyclization of enol ethers is disclosed. The reactions occur via addition of difluoroacyl radicals to methylene‐2‐oxazolines and subsequent intramolecular base‐promoted homolytic alkyl substitution (BHAS) of the intermediate oxyl‐alkyl radicals. Initiation of the radical chain reaction is best achieved...
An efficient and green approach for synthesis of optically active amines was developed via asymmetric transfer hydrogenation of N-sulfonyl ketimines catalyzed by the chiral and lipophilic rhodium-amido complex on water. Higher reactivity and enantioselectivity were observed on the hydrogenation of the solid substrate in an aqueous suspension compared to organic homogeneous phases. In the heterogeneous...
