New Advances in Chemical Research, May 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

Ruthenium-catalyzed oxidative cyanation of tertiary amines with molecular oxygen in the presence of sodium cyanide and acetic acid gives the corresponding alpha-aminonitriles, which are highly useful intermediates for organic synthesis. The reaction is the first demonstration of direct sp3 C-H bond activation alpha to nitrogen followed by carbon-carbon bond formation under aerobic oxidation conditions. The catalytic oxidation seems to proceed by (i) alpha-C-H activation of tertiary amines by the ruthenium catalyst to give an iminium ion/ruthenium hydride intermediate, (ii) reaction with molecular oxygen to give an iminium ion/ruthenium hydroperoxide, (iii) reaction with HCN to give the alpha-aminonitrile product, H2O2, and Ru species, (iv) generation of oxoruthenium species from the reaction of Ru species with H2O2, and (v) reaction of oxoruthenium species with tertiary amines to give alpha-aminonitriles. On the basis of the last two pathways, a new type of ruthenium-catalyzed oxidative cyanation of tertiary amines with H2O2 to give alpha-aminonitriles was established. The alpha-aminonitriles thus obtained can be readily converted to alpha-amino acids, diamines, and various nitrogen-containing heterocyclic compounds.

Catalytically competent Ir, Re, and Ru complexes H2L 1-H2L6 with dicarboxylic acid functionalities were incorporated into a highly stable and porous Zr6O 4(OH)4(bpdc)6 (UiO-67, bpdc = para-biphenyldicarboxylic acid) framework using a mix-and-match synthetic strategy. The matching ligand lengths between bpdc and L1-L 6 ligands allowed the construction of highly crystalline UiO-67 frameworks (metal-organic frameworks (MOFs) 1-6) that were doped with L 1-L6 ligands. MOFs 1-6 were isostructural to the parent UiO-67 framework as shown by powder X-ray diffraction (PXRD) and exhibited high surface areas ranging from 1092 to 1497 m2/g. MOFs 1-6 were stable in air up to 400 C and active catalysts in a range of reactions that are relevant to solar energy utilization. MOFs 1-3 containing [Cp*Ir III(dcppy)Cl] (H2L1), [Cp*Ir III(dcbpy)Cl]Cl (H2L2), and [Ir III(dcppy)2(H2O)2]OTf (H 2L3) (where Cp* is pentamethylcyclopentadienyl, dcppy is 2-phenylpyridine-5,4?-dicarboxylic acid, and dcbpy is 2,2?-bipyridine-5,5?-dicarboxylic acid) were effective water oxidation catalysts (WOCs), with turnover frequencies (TOFs) of up to 4.8 h -1. The [ReI(CO)3(dcbpy)Cl] (H 2L4) derivatized MOF 4 served as an active catalyst for photocatalytic CO2 reduction with a total turnover number (TON) of 10.9, three times higher than that of the homogeneous complex H 2L4. MOFs 5 and 6 contained phosphorescent [Ir III(ppy)2(dcbpy)]Cl (H2L5) and [RuII(bpy)2(dcbpy)]Cl2 (H2L 6) (where ppy is 2-phenylpyridine and bpy is 2,2?-bipyridine) and were used in three photocatalytic organic transformations (aza-Henry reaction, aerobic amine coupling, and aerobic oxidation of thioanisole) with very high activities. The inactivity of the parent UiO-67 framework and the reaction supernatants in catalytic water oxidation, CO2 reduction, and organic transformations indicate both the molecular origin and heterogeneous nature of these catalytic processes. The stability of the doped UiO-67 catalysts under catalytic conditions was also demonstrated by comparing PXRD patterns before and after catalysis. This work illustrates the potential of combining molecular catalysts and MOF structures in developing highly active heterogeneous catalysts for solar energy utilization.

PRMT4 is a type I protein arginine methyltransferase and plays important roles in various cellular processes. Overexpression of PRMT4 has been found to be involved in several types of cancers. Selective and in vivo effective PRMT4 inhibitors are needed for demonstrating PRMT4 as a promising therapeutic target. On the basis of compound 6, a weak dual PRMT4/6 inhibitor, we constructed a tetrahydroisoquinoline scaffold through a cut-and-sew scaffold hopping strategy. The subsequent SAR optimization efforts employed structure-based approach led to the identification of a novel PRMT4 inhibitor 49. Compound 49 exhibited prominently high potency and selectivity, moderate pharmacokinetic profiles, and good antitumor efficacy in acute myeloid leukemia xenograft model via oral administration, thus demonstrating this compound as a useful pharmacological tool for further target validation and drug development in cancer therapy.

Synthesis of the C?C bonds of ketones relies upon one high-availability reagent (carboxylic acids) and one low-availability reagent (organometallic reagents or alkyl iodides). We demonstrate here a ketone synthesis that couples two different carboxylic acid esters, N-hydroxyphthalimide esters and S-2-pyridyl thioesters, to form aryl alkyl and dialkyl ketones in high yields. The keys to this approach are the use of a nickel catalyst with an electron-poor bipyridine or terpyridine ligand, a THF/DMA mixed solvent system, and ZnCl2 to enhance the reactivity of the NHP ester. The resulting reaction can be used to form ketones that have previously been difficult to access, such as hindered tertiary/tertiary ketones with strained rings and ketones with alpha-heteroatoms. The conditions can be employed in the coupling of complex fragments, including a 20-mer peptide fragment analog of Exendin(9?39) on solid support.
