✦ Synopsis

Abstract

Molecular triads, B‐A‐B, in which the central unit A is aromatic or heteroaromatic, can exist as syn or anti conformers or atropisomers of correspondingly C or S shape. These stereoisomers are either discrete conformer species, often distinguished by NMR spectroscopy, or can be separated at ambient temperature as stable atropisomers. In the latter case syn and anti stereoisomers exhibit different (e.g., complex‐forming) properties. Practical applications of atropisomeric triads as ligands in asymmetric dihydroxylation are also discussed. Chirality 14:689–702, 2002.

Application of the principles of physical organic chemistry to the construction of molecule-based magnets is discussed. Not only the magnetic structures of conventional magnets but also secondary and tertiary structures of biopolymers are instrumental in the molecular design.
