Nine 3-aryl-5r-aryl-6t-carbethoxycyclohex-2-enones 2a-2i have been synthesized. For all these compounds, (1)H and (13)C NMR spectra have been recorded. For two compounds, 2D spectra have been recorded. The spectral data suggest that these compounds adopt sofa conformation in solution with H-5, H-6 and H-4t occupying axial-like positions and H-4c occupying equatorial-like positions. In 3-phenyl-5r-
