Abstract
The stereochemical phenomenon that arises from hindered rotation around bonds in nonplanar molecules is termed atropoisomerism.] The presence of a stereogenic axis is the distinct feature in these molecules. One type of atropoisomeric molecule is generated when bulky substituents are placed at the ortho positions of an aryl ring such that there is restricted rotation around the biaryl bonds.File in questo prodotto:
