A five-step synthesis of the water-soluble chiral polydentate ligand, (S)-PDTA [(S)-PDTA = N,N,N',N'-tetrakis[(hydroxycarbonyl)methyl]-(S)-1,2-diaminopropane] starting from L-alanine has been worked out, via steps with retention of chirality. Total yield is 50.7% (average of similar to 88% for each step), while published methods report 33.4% total yield over four steps. (c) 2009 Published by Elsevier Ltd.
