| 摘要 |
<p>The present invention provides new processes for the preparation of unsubstituted and substituted 4-amino-2-(2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione compounds which are useful, for example, for preventing or treating diseases or conditions related to an abnormally high level or activity of TNF-±. The invention can provide improved and/or efficient processes for the commercial production of unsubstituted and substituted 4-amino-2-(2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione compounds, including, but not limited to, unsubstituted 4-amino-2-(2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione.</p> |
