(S)-(-)-1 2-Diaminopropane dihydrochloride (CAS# 19777-66-3) Information

Overview (S)-(-) -diaminopropane dihydrochloride inogona kushandiswa semishonga synthesis yepakati, yakadai sekugadzirira kweDexrazoxane, iyo inonzi dextrorotatory enantiomer ye antitumor drug razoxane. Nokuda kwemishonga yekudzivirira mwoyo, kliniki yekudzivirira kweAnthracycline anticancer zvinodhaka zvinokonzerwa nehutu hwemwoyo uye leukemia muvana nekuda kwekemotherapy inokonzerwa nekukuvara kwemoyo, kazhinji semubatsiri mukurapa kenza.
Shandisa (S)-(-)-diaminopropane Dihydrochloride is an organic intermediate, inogona kugadzirwa nekuita D-(-)-tartaric acid uye propylenediamine.
Iyo diamine yakashandiswa mukugadzirwa kwechiral imidazoline makomponi
kugadzirira kugadzirira kwe(S)-(-)-diaminopropane dihydrochloride: wedzera 30.0gD-(-)-tartaric acid uye 8.0 ml mvura uye g(±) -1, 2-propanediamine muflask inopindura, kurunga kunyungudika, kutonhorera, wedzera Dropwise, tembiricha yakasimudzwa kuti reflux kwemaawa maviri nekukurudzira. Kukurudzira kwakamiswa, uye tembiricha yakasimudzwa kusvika 80 ° C. Kweawa imwe. Zvadaro, tembiricha yakaderedzwa zvishoma nezvishoma uye zvishoma nezvishoma kusvika kune kamuri tembiricha, kusvetwa, uye vacuum yakaomeswa kuwana 16.1g ye(S) -1, 2-propanediamine ditartrate. Wedzera 16.1g ye (S) -1, 2-propanediamine ditartrate uye yemvura kune reaction flask, nyunguduka nekupisa, wobva wawedzera mhinduro ye 7.43g ye potassium chloride uye 20ml yemvura, musanganiswa wakamutswa pa 70 °c. kwemaawa maviri. Mushure mekutonhora, firiji yakabvumirwa kumira kuti iite crystallization. Iyo filtrate yakasefa nekusveta uye yakanyungudutswa kuoma pasi pekumanikidzwa kwakaderedzwa kupa 84% G yeroro yakasimba (3), goho 4.02, [α] 20D = - ° (C = 1%, H2O).
