Compound: (S)-Propane-1,2-diamine dihydrochloride, is researched, Molecular C3H12Cl2N2, CAS is 19777-66-3, about Resolution of propandiamine and synthesis of dexrazoxane. Author is Wang, Yuling; Song, Hongrui; Song, Aihua.
The resolution of propandiamine and synthesis of dexrazoxane were studied. Using 1,2-propandiamine as primary material, the synthetic method of dexrazoxane by resolution, alkylation and cyclization was established. The L-tartaric acid was used as a resolving reagent, 1,2-propandiamine was resolved and the (+)-enantiomer was obtained. The method of changing 1,2-propandiamine bitartrate into hydrochloride was improved. The method was simpler and might be of application.
