A copper-catalyzed regioselective C–H selenylation of quinolines with readily available diaryl diselenides is developed based on a chelation-controlled radical cross-coupling strategy. The reaction is scalable, tolerates a wide spectrum of functional groups, and proceeds with excellent C5 regioselectivity to deliver selenoquinolines in high yields (up to 98 %). A single electron transfer (SET) mediated
regioselective halogenation of anilides and quinolines with heterogeneous Cu‐MnO catalyst and under irradiation with a household 40 W incandescent lamp was developed. The catalyst is recyclable, acetonitrile as an industrially friendly solvent, and economic N‐halo succinimides as a halogenating source. The reaction is scalable and well tolerated with a broad range of functional groups.
We report the synthesis of carbazole-based unnatural α-aminoacid and non-α-amino acid derivatives via a Pd(II)-catalyzed bidentate directing group 8-aminoquinoline-aided β-C(sp3)–H activation/functionalization method. Various N-phthaloyl, DL-, L- and D-carboxamides derived from their corresponding α-aminoacids, non-α-amino acids and aliphatic carboxamides were subjected to the β-C(sp3)–H functionalization
