Blap. Devi et M. Nagarajan, SYNTHESIS OF PENDANT POLYAMINOPOLYCARBOXYLIC ACID CROWN-ETHERS - POTENTIAL LIGANDS FOR MRI CONTRASTING AGENTS, Journal of the Chemical Society. Perkin transactions. I, (10), 1997, pp. 1495-1500
The pendant polyamino crown ethers 8 and 11 and polyaminopolycarboxyli
c acid crown ethers 12 and 15, potentially useful as ligands for MRI c
ontrasting agents as well as NMR shift reagents, have been synthesized
from pentaerythritol.
