SYNTHESIS OF FLUORINATED α-AMINO KETONES. PART II: α-ACYLAMINOALKYL α',α'-DIFLUOROALKYL KETONES

The synthesis of α-acylaminoalkyl 1.1-difluoro-3-butenyl ketones 2 is described.Reaction of substituted 5(4H)-oxazolones 4, obtained from α-amino acids, with 2.2-difluoro-4-pentenoic acid anhydride 3 (for R2=C6H5) or with 2.2-difluoro-4-penteno
