Non‐redox Lewis Acids Supported Pd‐Catalyzed C—C /C—H Activation and Accession to Produce Pharmaceutical Intermediates

ChemistryOpen, Volume 15, Issue 4, April 2026.
Palladium is a simple and versatile redox‐active metal that plays a crucial role in the oxidation reactions for organic synthesis and production of pharmaceutical intermediates. Notably, there has been significant progress with Lewis acids (LAs), which are non‐redox metal ions promoting Pd(II)‐catalyzed oxidation via C—H and C—C bond activation.

Solid-Phase Synthesis of Diverse Macrocycles By Regiospecific 2-Pyridone Formation: Scope and Applications

This study introduces a novel solid-phase macrocyclization method generating 2-pyridone rings. This method relies on the intramolecular condensation between secondary and tertiary dimethoxy-propionic amide (DMPA) units.

Solid-State Supramolecular Assembly of Salicylic Acid and 2-Pyridone, 3-Hydroxypyridine or 4-Pyridone

, 2017
Mechanochemical milling of equimolar mixtures of salicylic acid with three hydroxy derivatives of pyridine provided three new phases. With 2-hydroxypyridine, which is in fact present as 2-pyridone, a discrete cocrystal supramolecular assembly is formed ...
