SYNTHESIS OF FLUORINATED α-AMINO KETONES PART I: α-BENZAMIDOALKYL MONO- DI- AND TRIFLUOROMETHYL KETONES

Kolb, Michael,Barth, Jacqueline,Neises, Bernhard

, p. 1579 - 1582 (2007/10/02)

2-Phenyl-5(4H)-oxazolones, obtained from α-amino acids, are reacted with di- and trifluoro acetic anhydride by a modified Dakin-West procedure to yield in a one-pot reaction α-benzamidoalkyl-di- and trifluoromethyl ketones in good yields.The monofluoromethyl analogues were also prepared from α-amino acids, however the use of the highly toxic fluoroacetic anhydride was avoided.The key step is the halogen exchange reaction on the corresponding bromomethyl ketone.
