Abstract

The synthesis, separation and stereochemistry of 1-epimeric (±)-1-thioflavanone 1-oxide isomers with equatorial phenyl group are described. The higher melting isomer (2a) has a l,2-cis-, the lower melting one (2b) a 1,2-trans configuration. 1H NMR and mass spectral data for both isomers and X-ray diffraction analysis of 2a are also presented.
