Synthesis of Crosslinked Biopolyesters Catalyzed by Natural Amino Acids

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Highly crosslinked bio‐polyesters were synthesized via the ROCOP reaction between epoxidized sunflower oil and biobased cyclic anhydrides. The resulting materials were comprehensively characterized by FT‐IR, TGA, and DSC. A cross‐linked network in the bio‐based polymers has been confirmed by dynamic mechanical analysis.

Azuperylene: The Nonalternant Isomer of Perylene

open access: yesAngewandte Chemie, EarlyView.
As a nonalternating isomer of perylene, azuperylene (AP) is formed by the C─H/C─I coupling reactions we developed at the 1,8‐positions of azulene. The aromatic characteristics of the initial azulene are retained, and side chain modifications regulate the stacking pattern. The core of AP has smaller mutual perturbation compared to perylene.

Molecular Profiling and Tumor Microenvironment in Sinonasal Mucosal Melanoma as Biomarkers for Enhanced Prognostic Stratification

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Sinonasal mucosal melanoma (SNMM) is a rare and aggressive melanoma subtype with a notably poor prognosis. Despite molecular characterization advances, SNMM remains clinically challenging, highlighting the need for detailed molecular profiling.

Ligand‐Controlled Chemoselectivity in the Rhodium‐Catalyzed Synthesis of Pentafulvenes via (2 + 2 + 1) Alkyne Cyclotrimerization

open access: yesAngewandte Chemie, EarlyView.
Chemoselectivity Challenge: A precise catalyst design allows for chemoselectivity control over alkyne reactivity to yield pentafulvenes via (2 + 2 + 1) cyclotrimerization. Operative mechanism has been elucidated by means of stoichiometric and deuteration experiments, as well as DFT calculations.
