The present invention provides a methods and compounds for producing an enantiomerically enriched α-(phenoxy)phenylacetic acid compound of the formula:
from a mixture of its enantiomers, where R
1
is alkyl or haloalkyl and X is halide.
The preparation of α-nitroepoxides from nitro olefins and hydrogen peroxide in the presence of base is reported and the behaviour of this new chemical species towards selected nucleophiles, acids and reducing agents is described. Mass spectral data is also presented.
