| titleOfInvention |
Preparation of glutaric acid derivatives |
| abstract |
The invention provides a process for preparing a compound of the formula: <IMAGE> (I) or a base salt thereof, wherein R2 is hydrogen or C1-C6 alkyl optionally substituted by up to 3 substituents each independently selected from the group consisting of C1-C6 alkoxy and C1-C6 alkoxy(C1-C6 alkoxy)-; and R3 is C1-C6 alkyl or benzyl, said benzyl group being optionally ring-substituted by up to 2 nitro or C1-C4 alkoxy substituents comprising reacting a compound of the formula: <IMAGE> (II) wherein R1 is C1-C4 alkyl, phenyl or benzyl or C1-C4 alkoxy; and R2 and R3 are as previously defined for a compound of the formula (I), with hydrogen peroxide or a source of peroxide ions: said process being optionally followed by conversion of the compound of the formula (I) to a base salt thereof. The present invention also relates to novel compounds of the formula (II). |
