ABSTRACT:
The present invention discloses a structure of camphor-derived chiral auxiliary with a general formula (I),wherein R1and R2groups are independently hydrogen or C1to C10alkyl, X group is oxygen, two hydrogen atoms, or sulfur, and Y group is a functional group with stereo effect. Moreover, this invention also discloses a method for forming the above-mentioned chiral auxiliary.
