Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Synthesis of 1, 4-dihydropyridines (DHP) Catalyzed by Trichloroisocyanuric Acid (TCCA) in Aqueous Media [PDF]

Scientia Iranica, 2016
An array of 1, 4-dihydropyridines (DHP) derivativeswas synthesized by Hantzsch three-component reaction of aromatic aldehydes, ethyl acetoacetate and ammonium acetate using trichloroisocyanuric acid (TCCA) as an efficient catalyst in aqueous media. The proposed method was operationally simple and to make the process benign for the environment, water ...

Considerations for drug trials in hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1095-1112, April 2025.
Abstract Hypertrophic cardiomyopathy (HCM) is a heterogeneous condition with potentially serious manifestations. Management has traditionally comprised therapies to palliate symptoms and implantable cardioverter‐defibrillators to prevent sudden cardiac death. The need for disease‐modifying therapies has been recognized for decades.
