In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 20375-65-9, name is 3-Phenyl-6-chloropyridazine, introducing its new discovery. name: 3-Phenyl-6-chloropyridazine
The invention relates to a 2 – methyl serine of the preparation method. The main solves existing synthetic method with a long, complicated to operate, is not conducive to large-scale production the technical problem. Preparation method of this invention comprises the following steps: Cbz – chiral c acid with the benzaldehyde dimethyl acetal in thionyl chloride and zinc chloride under the effect of the reaction, the reaction product is crystallized to obtain intermediate 1, intermediate 1 with the chloromethyl benzyl in the alkaline reagent under the cooperation of the reaction to obtain the intermediate 2, intermediate 2 in lithium hydroxide obtained under the action of the intermediate 3, intermediate 3 finally palladium catalytic hydrogenolysis to obtain the final product 2 – methyl – serine. Through this invention can obtain high-purity 2 – methyl serine. (by machine translation)
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 20375-65-9, and how the biochemistry of the body works.name: 3-Phenyl-6-chloropyridazine
