<p>A process for producing an isooxazolidinedione compound [11] useful as a diabetic remedy wherein R is an optionally substituted aromatic hydrocarbon group, optionally substituted alicyclic hydrocarbon group, optionally substituted heterocyclic group, or optionally substituted fused heterocyclic group. The process, which is industrially utilizable, comprises using β-methyl L-aspartate as a starting compound to produce the target compound [11] in a high yield via a compound [6] which is an important intermediate wherein R is the same as the above.</p> |
