Studies on the NMR methodology for characterizing the structure of polymers and biopolymers based on the understanding of the NMR chemical shift/structure correlation using solution-state and ...

The catalytic enantioselective synthesis of 3-aryl-substituted pyrrolopyrimidines (PPYs), a common motif in drug discovery, is achieved through a kinetic resolution via quaternary ammonium ...

The Hammett substituent parameter (σp) is fundamental to physical organic chemistry but often suffers from inconsistencies in experimental determination across diverse substituents. This study ...
