Photoredox asymmetric catalytic enantioconvergent substitution of 3-chlorooxindoles

An enantioconvergent substitution of 3-substituted 3-chlorooxindoles with N-aryl glycines under visible light irradiation is reported. A transition-metal-free cooperative catalysis platform with a dicyanopyrazine-derived chromophore (DPZ) as a photoredox catalyst and a chiral Br?nsted acid catalyst is effective for these transformations, which involve a single-electron transfer redox step and an enantioselective radical coupling. A variety of valuable chiral 3-aminomethylene-3-substituted oxindoles can be directly synthesized with high yields and enantioselectivities.

A mild thermal and acid-catalyzed rearrangement of O-aryl ethers into ortho-hydroxy arenes

(Chemical Equation Presented) An unusual rearrangement of an O-aryl ether to an ortho-hydroxyaryl system was discovered during our studies on the synthesis of diazonamide A. We discuss the exploration of this rearrangement under mild thermal and both Bron
