ChemSusChem, Volume 19, Issue 11, 15 June 2026.High‐performing materials are required to achieve efficient energy storage; however, their environmental benefits can be undermined if toxic/corrosive chemicals, or high water usage, are required for their preparation. We present an environmentally friendly route to hierarchical porous carbon from starch, using carbon dioxide (CO2) as a mild activating

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.A practical and scalable route to C1 and C2 lysine homologs has been developed using Hofmann degradation of N‐protected L‐asparagine and L‐glutamine as the key step. These short‐tether scaffolds enable efficient synthesis of diverse Fmoc‐protected noncanonical amino acids (ncAAs) bearing donor, acceptor, redox‐active, and fluorescent residues.

Exploring Diverse Glycone Preferences of Aspergillus rutinosidases
Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.Rutinosidases from Aspergillus niger (AnRut) and A. oryzae (AoRut) catalyze hydrolysis and transglycosylation with non‐natural glycosides as donors, enabling glycosylation of alcoholic and phenolic acceptors. AnRut exhibits broad glycone promiscuity, while AoRut has a narrower substrate scope.

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.The catalytic carbonylation of alkynes is a powerful route to heteroaromatic scaffolds, yet achieving regioselectivity remains challenging. Herein, we report a divergent carbonylative cyclization of 2‐alkynylphenol derivatives that affords either coumarins (6‐endo‐dig) or 2‐coumaranones (5‐exo‐dig) by tuning the palladium‐based catalytic system. Pd(OAc)

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.Hydroxyl‐terminated MXene is integrated with a redox‐active covalent organic framework through electrostatic self‐assembly followed by hydrothermal treatment to construct MXene/COF heterostructures with a built‐in interfacial electric field. Termination‐controlled interfacial electronic modulation induces charge redistribution and favorable band ...
