Diastereoselective Synthesis of Highly Substituted Methylene Cyclobutanes by Pd Catalysis
European Journal of Organic Chemistry, EarlyView.A chemo‐ and diastereoselective palladium‐catalyzed intramolecular coupling/cyclization of borylated 1,5‐dienes, readily accessible by allene allylboration, with iodoarenes enables the synthesis of highly substituted methylene cyclobutanes. The method exhibits broad scope, high functional group tolerance, and complete enantiospecificity.

Biomimetic Construction of Abiotic Membranes Through Acylation of Cationic Diamino Acids [PDF]
ChembiochemCells produce membrane‐forming phospholipids through complex enzymatic pathways. Here, we present the in situ synthesis of a novel class of abiotic phospholipid analogs (APAs) featuring a permanent choline‐mimetic cation on diamino acid backbones.

Macromolecular Rapid Communications, EarlyView.We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...

Small, EarlyView.Cationic lipopeptides self‐assemble into stable, cell‐like vesicles that merge peptide programmability with lipid self‐organization. These biocompatible compartments efficiently sequester and deliver nucleic acids, enabling high transfection efficiency with low‐toxicity in both HEK293T cells and mesenchymal stem cells (MSCs).
