Transitioning Formamide Solvothermal Syntheses of MOFs to Less Toxic Solvents
Chemistry – A European Journal, EarlyView.Metal‐organic Frameworks (MOFs) are commonly synthesized in toxic formamide solvents. This study investigates the synthetic factors required for effective removal of formamides across various classes of MOFs, providing a foundation for designing new sustainable MOF syntheses.

Chemistry – A European Journal, EarlyView.In this work, the synthesis and characterization of novel π‐extended phenazine diimides is reported. The derivatives undergo differential reduction to a dihydrophenazine or Meisenheimer form depending on the reaction conditions employed. The outcome of this work highlights the paramount importance of structural design in determining the nature of the ...

It's a Gas: Bioconjugation With Vapor‐Phase Reagents
Chemistry – A European Journal, EarlyView.Gaseous reagents are an emerging class of bioconjugation reagents that can offer alternative selectivity paradigms for the construction of precise bioconjugates. A variety of both inert and highly reactive gases have recently been developed for bioconjugation use.

Elucidating the Solvent-Dependent Solvation and Structural Stability of Irinotecan: A Molecular Simulation Study. [PDF]
ChemphyschemThe solvation preference of irinotecan is governed by a competition between cavity formation and electrostatic stabilization. Computations reveal that the high cost of breaking water's hydrogen bond network outweighs its electrostatic benefits. In contrast, polar aprotic solvents (e.g., pyridine) offer an optimal thermodynamic balance, providing strong

N-1 regioselective Michael-type addition of 5-substituted uracils to (2-hydroxyethyl) acrylate
Beilstein Journal of Organic Chemistry, 2007 N-1 regioselective Michael-type addition of 5-substituted uracils to (2-hydroxyethyl) acrylate is presented. The reactions were performed in polar aprotic solvents and with avoidance of polymerization of acrylic substrate.
