Abstract :
The chiral shift reagents Sm-(R)-pdta and Sm-(S)-pdta, which are based on (R)- or (S)-1,2-diaminopropane-N,N,N′,N′-tetraacetic acid were synthesized from easily accessible compounds in three simple steps, which makes the method suitable for laboratory-scale production. In addition, a new and efficient method for the preparation of pure anhydrous (R)- or (S)-1,2-diaminopropane-N,N,N′,N′-tetraacetic acid was developed.
