Production Method of a-Methylene Lactone |
| abstract |
The present invention relates to a production method of α-methylene lactone which comprises the following steps: (A) a step of producing an enolate intermediate by making lactone react with alkyl formate under the presence of an alkoxide base; and (B) making the enolate intermediate react with paraformaldehyde. The production method of the present invention is capable of reducing the process time, improving yield, and minimizing the contamination of a reactor. |
