A. published an article.Recommanded Product: 73590-85-9 The title of the article was Synthesis of optically active omeprazole by catalysis with vanadyl complexes with chiral Schiff bases. And the article contained the following:
A new method for the preparation of optically active omeprazole I via asym. oxidation of the corresponding sulfide with the use of vanadyl complexes with chiral Schiff bases as the catalysts has been elaborated. The best yields and enantioselectivity of the oxidation were achieved using the complex of VO(acac)2 with ligand II. The experimental process involved the reaction of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole(cas: 73590-85-9).Recommanded Product: 73590-85-9
The Article related to enantioselective omeprazole preparation, Heterocyclic Compounds (More Than One Hetero Atom): Imidazoles and other aspects.Recommanded Product: 73590-85-9
