Witryna5 sie 2013 · Classic resolution of enantiomers from a racemic mixture requires the formation and physical separation of diastereomers, which differ in physical properties and are therefore separable, followed by removal of the resolving agent. ... The resolution of racemic ibuprofen (44) was studied by partial diastereomeric salt formation. WitrynaRacemic ibuprofen is an important NSAID used in the treatment of pain and inflammation in a variety of musculoskeletal and rheumatic disorders. The metabolism of ibuprofen, and that of a number of the related 2-arylpropionic acid NSAIDs, involves chiral inversion of the relatively inactive R-enantiomers to their active S-antipodes, …
