Preparation of isocoumarin derivatives and intermediates for the synthesis thereof |
| abstract |
A method of preparing optically active isocoumarin-3-yl-acetic acidnderivatives represented by Formula (I):n nwherein a specific isocoumarin-ketene derivative is subjected to an additionnreaction with an optically active alcohol, and then the ester thus obtained isnsubjected to a hydrolysis reaction. An intermediate for synthesis usedntherein. A method of preparing isocoumarin-3-yl-acetic acid derivativesnrepresented by Formula (III):n nwherein a specific isocoumarin derivative is subjected to an additionnreaction with carbon monoxide and oxygen in the presence of a transitionnmetal catalyst. An intermediate for synthesis used therein. |
