Synthesis of new fluorinated proline analogues from polyfluoroalkyl beta-ketoacetals and ethyl isocyanoacetate
Chem. Commun. 2018, 54 (69), 9683-9686
The reaction of trifluoroaldol acetal and other polyfluoroalkyl β-ketoacetals with ethyl isocyanoacetate was applied for the preparation of hitherto unknown fluorinated amino acids, cis- and trans-3-CF3/C2F5-prolines as well as trans-3-CF2Br/CF2Cl/CHF2-3-hydroxyprolines.
