A potential chiral derivatizing agent for 1,2-diglycerides
摘要:
Several chiral naphthylacetic acids have been prepared and evaluated as chiral derivatizing reagents for chiral alcohols. Fluorinated acids provide good general HPLC separations of chiral alcohols, especially 1,2-diglycerides. The separations and the F-19-NMR shift differences of pairs of diastereomers are documented.

The enzymatic hydrolysis of methyl 2-fluoro-2-arylpropionates was performed using lipases from Candida rugosa and Candidacylindracea (OF-360). A careful analysis of the reaction products revealed that racemic 2-hydroxy-2-arylpropionic acid and traces of 2-arylacrylic acid are formed, in addition to the expected 2-aryl-2-fluoropropionic acid. The presence of powerful electron-releasing groups in the
