In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of optically active omeprazole by catalysis with vanadyl complexes with chiral Schiff bases, published in 2008-08-31, which mentions a compound: 73590-85-9, mainly applied to enantioselective omeprazole preparation, COA of Formula: C17H19N3O2S.
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.
In some applications, this compound(73590-85-9)COA of Formula: C17H19N3O2S is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
