Florini, Nicola; Arnaud, Gaelle F.; Konya, Balint; Zucchi, Claudia; Palyi, Gyula published an article about the compound: (S)-Propane-1,2-diamine dihydrochloride( cas:19777-66-3,SMILESS:C[C@H](N)CN.[H]Cl.[H]Cl ).COA of Formula: C3H12Cl2N2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:19777-66-3) through the article.
A five-step synthesis of the water-soluble chiral polydentate ligand, (S)-PDTA (I) starting from L-alanine has been worked out, via 5 steps with retention of chirality. The total yield is 50.7% (average of ∼88% for each step), while published methods report 33.4% total yield over four steps.
