Process for producing 3-dpa-lactone |
| abstract |
A process for producing 3-DPA-lactone, which is difficult to obtain in a large amount from natural sources, from an easily available starting material in a high yield readily and selectively in a fewer steps than the conventional production processes. The process comprises protecting the hydroxyl groups at the 2- and 5-positions of $g(g)-ribonolactone, eliminating the hydroxyl group at 3-position to form a double bond between the 2- and the 3-positions, reducing this double bond, and removing the protective groups from the protected hydroxyl groups. |
