DTPA derivatives modified with non-ester bond an a process for synthesizing them |
| abstract |
Provided are DTPA derivatives having five carbonyl groups, represented by the following formula (1). Further provided is a process for synthesizing a compound (1a) represented by the formula of a compound (1) in which R 2 is 2-alkenyl group (R 4 ). The process comprises the steps of performing esterification of DTPA, introducing an alkoxycarbonyl group and reacting with 2-alkenyl alkoxyformate in the presence of a palladium catalyst, thereby obtaining the compound (1a). |
