Popis: | 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 ∼88% for each step), while published methods report 33.4% total yield over four steps. |
