Microwave‐Assisted Organic Syntheses in Deep Eutectic Solvents: A Win‐Win Association for Sustainable Chemistry

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
In organic synthesis, deep eutectic solvents (DES) have demonstrated their ability to be used as reaction media for the development of reactions in line with green chemistry principles. This review presents an overview of microwave‐assisted organic synthesis in DES, highlighting the diversity of uses for these solvents, their role in mechanisms, the ...

Bis‐Furans: A Sustainable Source of Diverse Molecular Architectures

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
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

open access: yesAngewandte Chemie Novit, Volume 2, Issue 1, March 2026.
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 ...
