Li, Ao published the artcilePorphyrin-Catalyzed Oxidation of N-Substituted Tetrahydroisoquinolines to Dihydroisoquinolones, COA of Formula: C3H5BN2O2, the publication is Synlett (2021), 32(7), 679-684, database is CAplus.
A visible-light-induced direct α-oxygenation of N-substituted 1,2,3,4-tetrahydroisoquinoline derivatives has been successfully developed. Tetraphenylporphyrinatozinc(II) has been identified as an effective and inexpensive photocatalyst for this transformation with a wide range of substrates. This protocol provides a convenient route to the desired products I (Ar = C6H5, pyrazol-3-yl, 4-MeC6H4, etc.; R = H, 6,7-OMe2) in moderate to good yields at room temperature under air.
