A synthesis has been developed for 2,7-dimethyl-1,8-di-o-tolylanthracene 4. The cis 4a and trans 4b isomers of this hydrocarbon can be separated and are stable to interconversion at temperatures below 200-degrees-C. The two enantiomers of the trans isomer 4b have chiral cavities and are expected to be useful precursors for chiral reagents or chiral catalysts.
