2,3-Dihydro-1H-pyrrolo[1,2-a]pyrrole-1,7-dicarboxylates of the formula, ##STR1## in which each R is independently H or lower alkyl, are prepared from from di(lower alkyl) 1,3-acetone-dicarboxylates.
公式为 ##STR1## 的2,3-二氢-1H-
吡咯并[1,2-a]
吡咯-1,7-二
羧酸二(lower alkyl)酯,其中每个R独立为H或较低的烷基,是从di(lower alkyl)
1,3-丙酮二羧酸酯制备而来的。
