Catalytic Amyloids: Turning Fibrils Into Biocatalysts

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Synthetic Studies Towards Darobactin A

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
The urgent need for new antibiotics led us to develop a new methodology for the synthesis of the natural product darobactin A selectively targeting gram‐negative bacteria. This study provides new insights into the synthesis of strained indole‐containing macrocycles.

Bis‐Furans: A Sustainable Source of Diverse Molecular Architectures

European 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 ...
