2-oxetanone derivative and process for production thereof |
| abstract |
An aldehyde derivative represented by the general formula (2) is reacted with ketene in the presence of a Lewis acid catalyst to produce a novel 2-oxetanone derivative (1), which is then purified to a 2-oxetanone derivative having a high trans-isomer purity, and then converted to a vinyl derivative (3) through decarboxylation reaction. |
