Induction of molecular asymmetry by a remote chiral group
Article Abstract:
Chiral catalysts or stoichiometric amounts of chiral substrates are commonly used in methods of asymmetric synthesis of organic compounds. Invariably, the reacting components have to be very near the source of chirality. However, supramolecular chemistry has demonstrated that stereochemical information can be sent through greater distances than previously thought. The transmission of chiral information through as many as nine achiral connecting atoms is illustrated.

Compliments from Lord Kelvin
Article Abstract:
Lord Kelvin's classic definition of chirality emphasizes the non-superposability of a chiral object and its mirror image by the enantiomers of bromochlorofluoromethane, CHFClBr. Chirality discovered in the early years of the nineteenth century, is natural optical rotation of the plane of polarization of linearly polarized light by a chiral medium.
