Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 19777-66-3, is researched, SMILESS is C[C@H](N)CN.[H]Cl.[H]Cl, Molecular C3H12Cl2N2Journal, Tetrahedron: Asymmetry called Enantiomeric impurities in chiral catalysts, auxiliaries, synthons and resolving agents. Part 2, Author is Armstrong, Daniel W.; He, Lingfeng; Yu, Timothy; Lee, Jauh T.; Liu, Yan-song, the main research direction is enantiomeric purity chiral catalyst auxiliary synthon resolving agent.Reference of (S)-Propane-1,2-diamine dihydrochloride.
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.
