Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles
European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

MONDE·T: A database and interactive webserver for non‐standard amino acids and peptide components in the PDB [PDF]
Protein SciAbstract Non‐standard amino acids (ncAAs) together with synthetic additions (like caps and linkers) are of wide interest for protein design and pharmaceutical optimization, as they can improve physicochemical properties and possibly reshape protein structure. Their inclusion in experimental structures has not been explored systematically.

Visible‐Light‐Mediated Lewis Acid‐Catalyzed Diradical Hydrogen Atom Transfer Reaction of Enamides
Advanced Science, Volume 13, Issue 59, 23 October 2026.The Lewis acid catalysis was crucial for the success of the DHAT reaction of enamides by lowering the energy of the triplet excited state and modulating the reactivity of the formed diradical intermediate in a carbon‐to‐carbon 1,5‐DHAT and consequent cyclization that allows the functionalization of C(sp3)−H bonds to construct a variety of novel β ...

, 2023 L-Azetidine-2-carboxylic acid (AZE) is a non-protein amino acid that shares structural similarities with its proteogenic L-proline amino acid counterpart. For this reason, AZE can be misincorporated in place of L-proline, contributing to AZE toxicity. In

Ring opening of photogenerated azetidinols as a strategy for the synthesis of aminodioxolanes
Beilstein Journal of Organic Chemistryα-Aminoacetophenones are identified as promising building blocks for the synthesis of highly substituted dioxolanes. The presented strategy is founded on the build and release of molecular strain and achieves a formal transposition of a methyl group ...
