Microwave-Assisted Synthesis of Heterocycles via Rhodium(III)-Catalyzed C-H Activation: Norbornadiene as an Acetylene Equivalent.

General procedures for the rhodium-catalyzed annulation of aryl/heteroaryl -pivaloyl hydroxamic acids and norbornadiene have been developed. Employing norbornadiene as an acetylene equivalent enables utilization of diverse heterocyclic substrates for this transformation which fail to react or undergo competitive Lossen rearrangement under previously reported conditions. Microwave heating significantly reduces reaction times compared to conventional protocols and allows a one-step process to be realized.

In this study, we developed palladium-catalyzed dehydrogenative cyclization to transform 1-(2-aminoaryl)-3-arylpropan-1-ones into 2-arylquinolin-4(1)-ones, also known as aza-flavones which are the bioisosteres of flavones, in an atom-economic manner. This method exhibited excellent chemical compatibility with a broad substrate scope, accommodating up to 25 derivatives. Additionally, kinetic studies were performed to elucidate the reaction mechanism.

Solid electrolytes (SEs) are crucial for advancing next-generation rechargeable battery technologies, but their commercial viability is partially limited by expensive precursors, unscalable synthesis, or low ionic conductivity. Lithium tetrahaloaluminates offer an economical option but exhibit low Li conductivities with high activation energy barriers. This study reports the synthesis of lithium aluminum chalcohalide (LiAlClS) using inexpensive precursors one-step mechanochemical milling.

Department of Chemistry, Fudan University, 2005 Songhu Road, Shanghai 200438, PR China.
This study explores the deoxygenation of pyridine -oxides and presents a one-step photoredox method for the direct synthesis of 2-hydroxymethylated pyridines from pyridine -oxides. Mechanism studies elucidate the role of the catalyst and provide evidence of the possible electron transfer process and the formation of key radicals. A range of pyridine derivatives, particularly 2-hydroxymethyl-substituted pyridines, which may be difficult to obtain, can be synthesized in a single step.

Background: Cytokeratins are intracellular proteins known as diagnostic biomarkers or prognostic factors for certain cancers. Cytokeratin 19 (CK-19) expression has been proven to have prognostic value for some cancers, but its relationship with others, such as prostate cancer (PCa), remains unclear. This systematic review article aimed to examine the relationship between CK-19 expression and prostate adenocarcinoma (PAC).
