Abstract:
The racemic title compound, C34H32OS2, comprises an atropisomeric binaphthyl di-thio-acetal substituted at the methyl-ene carbon atom with a chiral benzyl alcohol. The two naphthalene ring systems are additionally substituted at the 3,3'-position with isopropyl groups. The overall stereochemistry is defined as aS,R and aR,S. The hydroxyl group forms an intra-molecular O-H⋯S hydrogen bond to one of the sulfur atoms. The crystal structure contains weak C-H⋯π inter-actions that link the mol-ecules into extended arrays.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
