Hybrid catalyst systems to achieve acceptorless dehydrogenation of N-heterocycles and tetrahydronaphthalenes-model substrates for liquid organic hydrogen carriers-were developed. A binary hybrid catalysis comprising an acridinium photoredox catalyst and a Pd metal catalyst was effective for the dehydrogenation of N-heterocycles, whereas a ternary hybrid catalysis comprising an acridinium photoredox catalyst, a Pd metal catalyst, and a thiophosphoric imide organocatalyst achieved dehydrogenation of tetrahydronaphthalenes. These hybrid catalyst systems allowed for 2 molar equiv of H2 gas release from six-membered N-heterocycles and tetrahydronaphthalenes under mild conditions, i.e., visible light irradiation at rt. The combined use of two or three different catalyst types was essential for the catalytic activity.

New Advances in Chemical Research, May 2021.

Targeting the nuclear receptor RORgammat is thought to be effective in autoimmune disorders. Tertiary sulfonamide 1 was found to be a potent RORgammat inverse agonist previously. However, the high hepatic clearance value limits its druggability. In this study, we designed and synthesized a series of N-sulfonamide-tetrahydroquinolines by molecular modeling and scaffold hopping strategy, aiming at improving the metabolic stabilities. Detailed SAR exploration led to identification of potent RORgammat inverse agonists such as 13 with moderate binding affinity and inhibitory activity of Th17 cell differentiation. Binding mode of 13 with RORgammat-LBD was revealed by molecular docking. Moreover, 13 showed lower intrinsic clearance in mouse liver microsomes compared with 1 and potent in vivo efficacy and safety in psoriasis models, which can be used as a good starting point for the further optimization.

(Figure Presented) Only oxygen and acid! The oxidative coupling of xanthene and other activated benzylic compounds with carbon nucleophiles such as ketones, can be performed under ambient conditions without solvent by simply using oxygen and catalytic amounts of methanesulfonic acid. The proposed reaction mechanism involves substrate activation by formation of hydroperoxides; the method can therefore be regarded as an “autoxidative coupling reaction”.

Reported is an achiral CpxRhIII/chiral carboxylic acid catalyzed asymmetric C?H alkylation of diarylmethanamines with a diazomalonate, followed by cyclization and decarboxylation to afford 1,4-dihydroisoquinolin-3(2H)-one. Secondary alkylamines as well as nonprotected primary alkylamines underwent the transformation with high enantioselectivities (up to 98.5:1.5 e.r.) by using a newly developed chiral carboxylic acid as the sole source of chirality to achieve enantioselective C?H cleavage by a concerted metalation-deprotonation mechanism.

Significance: Proline catabolism refers to the 4-electron oxidation of proline to glutamate catalyzed by the enzymes proline dehydrogenase (PRODH) and l-glutamate gamma-semialdehyde dehydrogenase (GSALDH, or ALDH4A1). These enzymes and the intermediate metabolites of the pathway have been implicated in tumor growth and suppression, metastasis, hyperprolinemia metabolic disorders, schizophrenia susceptibility, life span extension, and pathogen virulence and survival. In some bacteria, PRODH and GSALDH are combined into a bifunctional enzyme known as proline utilization A (PutA). PutAs are not only virulence factors in some pathogenic bacteria but also fascinating systems for studying the coordination of metabolic enzymes via substrate channeling. Recent Advances: The past decade has seen an explosion of structural data for proline catabolic enzymes. This review surveys these structures, emphasizing protein folds, substrate recognition, oligomerization, kinetic mechanisms, and substrate channeling in PutA. Critical Issues: Major unsolved structural targets include eukaryotic PRODH, the complex between monofunctional PRODH and monofunctional GSALDH, and the largest of all PutAs, trifunctional PutA. The structural basis of PutA-membrane association is poorly understood. Fundamental aspects of substrate channeling in PutA remain unknown, such as the identity of the channeled intermediate, how the tunnel system is activated, and the roles of ancillary tunnels. Future Directions: New approaches are needed to study the molecular and in vivo mechanisms of substrate channeling. With the discovery of the proline cycle driving tumor growth and metastasis, the development of inhibitors of proline metabolic enzymes has emerged as an exciting new direction. Structural biology will be important in these endeavors.

A [4+2] cycloaddition reaction proceeding through tandem cross-dehydrogenative coupling/intramolecular hydroarylation between N-aryltetrahydroisoquinolines and crotonaldehyde was developed by virtue of enamine-iminium catalysis, which enabled the rapid construction of ring-fused tetrahydroquinolines. The first metal-free catalytic oxidative coupling of gamma-selective C(sp3)-H bonds of crotonaldehyde was realized by using a secondary amine catalyst and 2,3-dichloro-5,6-dicyanoquinone.
