ABSTRACT:
The present invention relates to novel optically active isoxazole derivatives represented by general formula: ##STR1## which are useful as intermediates for synthesis of prostaglandin and a process for producing the same as well as novel aldehyde compounds represented by general formula: ##STR2## which are intermediates for preparing the compounds [XI] described above and a process for preparation thereof. In the compounds shown by these formulae, R.sup.1 represents an alkyl group or a cycloalkyl group which may have an alkoxy group or a group shown by --Ra--A--B (wherein Ra is an alkyl group; A is a hetero atom or an single bond; and B is an aromatic or hetero ring which may have a substituent(s)); and R.sup.2 and R.sup.3, which may be the same or different, each represents an aralkyl group, a silyl group or an acyl group.
