One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Recommanded Product: Tris(dibenzylideneacetone)dipalladium-chloroform, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 52522-40-4, Name is Tris(dibenzylideneacetone)dipalladium-chloroform, molecular formula is C52H43Cl3O3Pd2
Containing quaternary carbon chiral center vinyl oxazolidone compound and its preparation method (by machine translation)
The invention provides a vinyl oxazolidinone compound containing a quaternary carbon chiral center and a preparation method thereof. According to the preparation method, vinyl glycol carbonic ester reacts with isocyanate in an organic solvent to prepare the vinyl oxazolidinone compound containing the quaternary carbon chiral center under the catalysis action of a palladium complex which is generated through the coordination of a palladium source and a chiral ligand and serves as a catalyst. The vinyl oxazolidinone compound containing the quaternary carbon chiral center, provided by the invention, has potential physiological activity and can be conveniently converted into amino alcohol containing the quaternary carbon chiral center, chirality quaternary carbon vinyl amino acid and chirality quaternary carbon serine. The preparation method provided by the invention is a high-efficiency environmentally-friendly asymmetric catalysis method and has the advantages of high catalytic activity, mild reaction conditions, convenience and easiness in availability of reaction raw materials and high enantioselectivity.
