Summary: This study reports the mechanistic investigation of the Rh-catalyzed cross-coupling reaction between vinylic ethers and aryl Grignard reagents. The presence of olefinic ligands significantly affects the catalytic activity of Rh precatalysts. Computational studies reveal that the reaction proceeds through Mg cation-assisted insertion/anti-beta-oxygen elimination, with the Mg countercation coordinating to the ethereal oxygen atom in the transition state.

Summary: This study presents a mechanistic investigation of the Rh-catalyzed cross-coupling reaction between vinylic ethers and aryl Grignard reagents. Kinetic studies reveal first-order and zeroth-order kinetics with respect to the vinyl ether and aryl Grignard reagents, respectively. Computational studies suggest that the reaction proceeds through Mg cation-assisted insertion/anti-beta-oxygen elimination. The results demonstrate the unique chemoselectivity of the Rh-catalyzed reaction.

Summary: Iodine-induced cleavage at phosphorothioate DNA has potential applications in detecting and sequencing bacterial DNA. However, the cleavage mechanism and specific selectivity at the modified site are not well established. This study reveals that iodine selectively binds to the sulfur atom of the phosphorothioate link and triggers P-O bond cleavage through phosphotriester-like hydrolysis. The cleavage process also results in unwanted P-S/P-O conversions and loss of the phosphorothioate handle.

Summary: In this study, density functional theory calculations were used to evaluate the influence of a dinuclear metal-metal interaction during aryl C-O bond reduction/defunctionalization catalyzed by a heterodinuclear Rh-Al complex. The calculations demonstrate the critical Rh-Al cooperative behavior necessary for aryl C-O bond activation and catalytic turnover. However, only the Rh metal center is involved in hydrosilane Si-H bond activation or B-B bond activation of B-2(pin)(2) to defunctionalize the substrate.

Summary: Hydrodeoxygenation of lignin-derived phenols can be achieved through three reaction pathways: tautomerization, direct ring hydrogenation, and direct C-O bond cleavage. A comparative study of direct C-O bond cleavage and direct ring hydrogenation was conducted using diphenyl ether on Pd/Fe, Fe, and Pd/C catalysts, with direct C-O bond cleavage showing dominant reaction rates on Pd/Fe despite higher activation energy compared to direct ring hydrogenation. The synergic catalysis of Pd-Fe was found to contribute to the higher rates of direct C-O bond cleavage on Pd/Fe.

Summary: Flavonoids have been found to influence circadian cycling and photosynthetic activity in plants. Deficiency or excessive levels of flavonoids can disrupt the normal functioning of the plant's circadian clock and chlorophyll cycling. These findings reveal a previously unknown connection between flavonoids and the plant circadian clock, and provide a foundation for further investigation into the molecular mechanisms of flavonoid action.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
