A PROCESS FOR PREPARING A CYCLOADDITION COMPOUND |
| 摘要 |
<p>A process for preparing a cycloaddition compound, which comprises reacting ketene with a carbonyl group-containing compound having formula (I), which contains a highly electron-attractant group in the alpha -position relative to the carbonyl group in the presence of a chiral tertiary amine as catalyst to form a cycloaddition compound having formula (II).</p> |
