Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 16251-45-9, Name is (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one, SMILES is O=C1O[C@H](C2=CC=CC=C2)[C@H](C)N1, belongs to oxazolidines compound. In a document, author is Tessier, Arnaud, introduce the new discover, HPLC of Formula: C10H11NO2.
2-Trifluoromethyl-2-methyl-4-phenyloxazolidine: A new chiral auxiliary for highly diastereoselective enolate alkylation
The alkylation reactions of an amide sodium enolate derived from a C-2 disubstituted trifluoromethylated oxazolidine (Fox) chiral auxiliary occurred in good yields with a very high diastereoselectivity (>98% de). Compared to the C-2 monosubstituted trifluoromethyl analogue, this chiral auxiliary is much more stable towards bases at temperature over -35 degrees C because the dehydrofluorination reaction is avoided. However asymmetric enolates quaternarization was not successfully achieved with this new chiral auxiliary. (C) 2011 Elsevier B.V. All rights reserved.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 16251-45-9 is helpful to your research. HPLC of Formula: C10H11NO2.
