Processes for preparing alkylene and dialkyl ketals and alkyl alpha-enol ethers of alpha-acetyl cinnamic acids or esters thereof |
| abstract |
Alkylene or dialkyl ketal of an alpha-acetyl cinnamic acid or ester therof are obtained by reacting alpha-acetyl cinnamic acid or an ester thereof with a ketalizing agent selected from the group consisting of alkyl glycols, dialkyl detals and trialkyl orthoesters in the presence of the transition metal catalyst and an acid catalyst. Also, alkyl alpha-enol ethers of alpha-acetyl cinnamic acid are obtained by heating the alkylene or dialkyl ketals. |
