Optically active isoxazole derivatives and intermediates for preparation thereof

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, R1 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 R2 and R3, which may be the same or different, each represents an aralkyl group, a silyl group or an acyl group.

New chiral synthetic intermediate for prostaglandins

Preparation of an optically active synthetic intermediate 3 starting from D-mannitol and its conversion to PGF2α (1) by using [3+2] cycloaddition of the nitrile oxide derivative of 3 followed by conjugate addition of the vinylzincate to exocyclic enone 2 are described.
