Elucidating the Structures of Substituted Adamantyl Esters and Ethers Using Rotational Spectroscopy and Computations

ChemPhysChem, EarlyView.
Five adamantyl esters and ethers with alkyl substituents of increasing branching are investigated by rotational spectroscopy. From the experimental data, their accurate structures are derived. All the derivatives feature similar CC distances, regardless of the functional group, the alkyl substituent, or other effects as methyl top internal rotation ...

Synthesis of New N,N′‐Diarylureas and Their Theoretical Study as Cannabinoid‐1 Receptor Inhibitors

ChemPlusChem, EarlyView.
A series of new pyrazolo‐ and triazolo‐based N,N′‐diarylureas is synthesized following the triphosgene protocol in the last step. Density functional theory calculations and molecular docking provide strong evidence that all new compounds bind strongly to the cannabinoid‐1 (CB‐1) receptor, showing comparable results with the known allosteric CB‐1 ...

Green Extraction and Fractionation of Chestnut Wood Waste: A Sustainable Pathway to Biopolymers and Antimicrobial Solutions

ChemSusChem, EarlyView.
A sustainable valorization of chestnut wood waste is proposed through microwave‐assisted subcritical water extraction, optimized via central composite design. The extract is fractionated by membrane filtration and resin purification, enabling water recovery (up to 89%) and obtaining a tannin‐rich fraction, used to synthesize a PVA‐based biopolymer ...

Trivalent Metal Lewis Acids Activate CO2 in Transfer Hydrogenations

ChemSusChem, EarlyView.
Indium(III) triflate and other trivalent metal ions catalyst the transfer hydrogenation of CO2 to formate and a series of in situ tandem reactions to yield formamides or azoles. In contrast to previous reports, the reaction proceeds by CO2 activation instead of hydride abstraction from a transfer hydrogenation source. Using γ‐terpinene as a bio‐derived
