In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Photoredox asymmetric catalytic enantioconvergent substitution of 3-chlorooxindoles, published in 2019, which mentions a compound: 4360-63-8, Name is 2-Bromomethyl-1,3-dioxolane, Molecular C4H7BrO2, Synthetic Route of C4H7BrO2.
An enantioconvergent substitution of 3-substituted 3-chlorooxindoles I (R = H, 6-Cl, 4-Br, 5-NO2, etc.; R1 = 4-FC6H4S(O)2, Me; Ar = Ph, naphthalen-2-yl, C6D5, etc.) with N-aryl glycines Ar1NHCH2C(O)OH [Ar1 = 4-methoxyphenyl, 4-methoxy-3-(trifluoromethyl)phenyl] 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 Bronsted 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 II can be directly synthesized with high yields and enantioselectivities.
