OPTICALLY-ACTIVE ALPHA-NAPHTHALENE AND BETA-NAPHTHALENE DERIVATIVES .4. SYNTHESIS AND OPTICAL PURITY OF 2-METHYL-3-(ALPHA-NAPHTHYL AND BETA-NAPHTHYL)-BUTANES AND 2,2-DIMETHYL-3-(ALPHA-NAPHTHYL AND BETA-NAPHTHYL)-BUTANES

The (S) methyl 3-(α- and β-naphthyl)-butanoates have been related to the optically active title compounds and to 2-(α- and β-naphthyl)-butanoic-, -3-methylbutanoic- and -3,3-dimethylbutanoic acids. The absolute configurations and maximum rotatory powers (this is in fact, all that has been measured, in terms of rotatory power) of the naphthyl hydrocarbons and their related compounds have been established. © 1979.
