摘要 |
2-Formyl-3,3-dimethylcyclopropylacetic acid is prepared by ozonolysis of 3-acetyl-6,6-dimethylbicyclo[3.1.0]-2-hexene followed by reductive cleavage of the ozonolysis product thus formed. The 3-acetyl-6,6-dimethylbicyclo[3.1.0]-2-hexene is prepared by contacting 2-(2-acetyl-3-oxobutyl)-3,3-dimethylcyclopropanecarbaldehyde with a base in the presence of a solvent.
