- Metal-Oxidant-Free Cobalt-Catalyzed C(sp2)-H Carbonylation of ortho-Arylanilines: An Approach toward Free (NH)-Phenanthridinones
-
A traceless directing group assisted Co-catalyzed C(sp2)-H carbonylation of ortho-arylanilines for the synthesis of free (NH)-phenanthridinones in metal-based-oxidant-free fashion was accomplished. This protocol employs diisopropyl azodicarboxylate as the CO source and oxygen as the sole oxidant, and provides good yields with various functional tolerance. The methodology has been applied for the total synthesis of PARP inhibitor PJ-34. Furthermore, the kinetic isotopic effect experiments reveal the C-H bond cleavage probably occurred in the rate-determining step.

- A para-C–H Functionalization of Aniline Derivatives via In situ Generated Bulky Hypervalent Iodinium Reagents
-
A practical para-C-H functionalization of aniline derivatives has been developed using an in situ generated bulky hypervalent iodinium reagent. Para-iodo, bromo, chloro, nitro, trifluormethyl aniline derivatives can be obtained efficiently, in many cases in 10 min in a transition metal-free manner. Medicinal chemicals or intermediates can be purified without column chromatography or recrystallization, which significantly reduces the waste and simplifies the work-up process.

- Palladium-Catalyzed C-H Activation and Cyclization of Anilides with 2-Iodoacetates and 2-Iodobenzoates: An Efficient Method toward Oxindoles and Phenanthridones
-
A concise approach to the synthesis of oxindoles and phenanthridones from anilides is described. In the presence of catalytic amount of Pd(OAc)2, 2-iodoacetates and 2-iodobenzoates can be used to functionalize ortho C-H bond of anilides, which subsequently undergo intramolecular cyclization to give the products. A possible reaction mechanism that involves a PdII/PdIV catalytic cycle is proposed with the support of detailed mechanistic studies.

- KOtBu mediated synthesis of phenanthridinones and dibenzoazepinones
-
Synthesis of substituted phenanthridinones and dibenzoazepinones has been realized from 2-halo-benzamides in the presence of potassium tert-butoxide and a catalytic amount of 1,10-phenanthroline or AIBN. This new carbon-carbon bond forming reaction gives direct access to various biaryl lactams containing six- and seven-membered rings chemoselectively. Carbon-carbon coupling seems to proceed by the generation of a radical in the amide ring which leads to C-H arylation of aniline.

- Investigation of Phenanthridone and Its Derivatives by Infrared Spectroscopy
-
Infrared spectroscopy has been used to investigate phenanthridone and its 2-bromo, N-methyl-, and nitro-derivatives.It is shown that the vibration frequencies of the NH- and CO-groups depend on the nature of the substituents, their position in the molecule, the state of aggregation, and the polarity of the solvent.Substitution in the 2- and 8-positions has hardly any effect on the tendency of the lactam group to form intermolecular hydrogen bonds; in 3-nitrophenantridone they are weakened, while in 4- and 2, 4-dinitrophenanthridone only intramolecular hydrogen bonds are formed.
