Webponding absolute conﬁguration to that of cryptochiral poly-styrenes in conjunction with asymmetric autocatalysis. Chirality plays a signiﬁcant role in chemical, biological, pharmaceutical and material science.1 The study of chirality has been developed as an innovative technique2 for distinguishing between a pair of enantiomers. In general, In stereochemistry, cryptochirality is a special case of chirality in which a molecule is chiral but its specific rotation is non-measurable. The underlying reason for the lack of rotation is the specific electronic properties of the molecule. The term was introduced by Kurt Mislow in 1977.
