Paragraph 0111-0116; 0133, (2019/12/25)
Disclosed is a method for preparing a chiral Gingerol compound. To prepare the chiral Gingerol compound, a racemic Gingerol compound is treated with kinetic resolution in the presence of a chiral catalyst compound and an alkali metal fluoride so a chiral Gingerol compound with high optical purity can be prepared. An oligo ethylene glycol-derived compound including an oligo ethylene glycol functional group, a basic part, and a hydroxy functional group of a binol derivative, an acidic part, can be used as a chiral catalyst compound.COPYRIGHT KIPO 2020

A straightforward synthesis of (S)-gingerols 1-3 has been described. The requisite stereogenic center in the target molecules was introduced by Sharpless asymmetric dihydroxylation using a chiral complex, AD-mix β. This route is simple and efficient to prepare the products in very good yields.
