Name: (S)-Propane-1,2-diamine dihydrochloride. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: (S)-Propane-1,2-diamine dihydrochloride, is researched, Molecular C3H12Cl2N2, CAS is 19777-66-3, about Enantiomeric impurities in chiral catalysts, auxiliaries, synthons and resolving agents. Part 2.
The enantiomeric purity of reagents used in asym. synthesis is of fundamental importance when evaluating the selectivity of a reaction and the product purity. In this work, 109 chiral reagents (many recently introduced) are assayed. Approx. 64% of these reagents had moderate to high levels of enantiomeric impurities (i.e. from >0.1% to <16%). The type of chiral reagents assayed and used in enantioselective synthesis include metal-ligand catalysts for allylic substitutions, catalysts for addition of Grignard reagents and other additions, epoxidations and reduction of ketones and aldehydes; Ru-complex auxiliaries for asym. cyclopropanation, as well as amine, diamine, alc., diol, amino alc., carboxylic acid and oxazolidinone auxiliaries; epoxide, lactone, furanone, pyrrolidinone, nitrile, sulfoximine and carboxylic acid synthons (including malic acid, mandelic acid, lactic acid and tartaric acid); and a variety of chiral resolving agents. Accurate, efficient assays for all compounds are given. From this literature《Enantiomeric impurities in chiral catalysts, auxiliaries, synthons and resolving agents. Part 2》,we know some information about this compound(19777-66-3)Name: (S)-Propane-1,2-diamine dihydrochloride, but this is not all information, there are many literatures related to this compound(19777-66-3).
