The present invention relates to new oxime carbamoyl derivatives of formula (I), processes for their preparation, and to pharmaceutical compositions containing them for the treatment of neurological disorders, such as neuropathic pain and anxiety.
Enamides were efficiently prepared via a novel Rh/C-catalyzed direct hydroacylation of ketoximes. Up to 88% isolated yield of enamides were obtained with this method. Subsequent asymmetric hydrogenation of the enamides with Rh/DuanPhos complex gave the corresponding chiral amine in excellent enantioselectivities (up to 99.7% ee).
