ABSTRACT:
The present invention provides special epoxy derivative (1), cyclohexanone derivative (2), cyclohexenone derivative (3) and 3-substituted cyclohexenone derivative (4) which are useful as intermediates for synthesizing physiologically active materials, and a method for stereoselectively introducing substituted groups. Further, the present invention provides a method for synthesizing optically active compounds, such as optically active carvone via these intermediates. ##STR1##
