Dihydropyridine derivatives modulate heat shock responses and have a neuroprotective effect in a transgenic mouse model of Alzheimer’s disease [PDF]
Heat shock proteins (Hsps) have chaperone activity and play a pivotal role in the homeostasis of proteins by preventing misfolding, by clearing aggregated and damaged proteins from cells and by maintaining proteins in an active state. Alzheimer’s disease

Bis‐Furans: A Sustainable Source of Diverse Molecular Architectures
A concise synthetic route to diverse acyclic and heterocyclic compounds has been developed by combining hetero‐Diels–Alder reactions, DBU‐promoted ring openings, and Lewis base‐catalyzed annulations. Nitrosoalkenes reacted with furan derivatives to form 4a,7a‐dihydro‐4H‐furo[2,3‐e][1,2]oxazines, which underwent DBU‐promoted rearrangements to 6H‐1,2 ...

Radical Retrosynthesis of Natural Products Enabled by Iron‐Based Reductive Olefin Coupling
This review highlights iron‐catalyzed reductive olefin coupling (ROC)—a strategy for C─C bond formation driven by metal‐hydride hydrogen atom transfer (MHAT)—as a key tool in natural products synthesis. This review surveys dozens of total syntheses employing ROC‐based strategies, highlighting its power to forge strained rings, quaternary centers, and ...
