Document Type and Number:
WIPO Patent Application WO/2017/023124
Kind Code:
A1
Abstract:
The present invention relates to a novel method for preparing a chromanol derivative. According to the present invention, unlike a conventionally known optically active reduction technique, a method for preparing a chromanol derivative having optical activity has advantages of: not needing an additional purification process since chromanol, to be prepared, exhibits a high optical purity; being favorable for mass production since no severe reaction conditions are contained and no dangerous reagents are used; and having an excellent preparation yield.
