The synthesis of both syn- and anti-diol epoxide metabolites of triphenylene has been achieved under complete stereochemical control commencing with commercially available 9-phenanthrol in 18% (9 steps) and 37% (8 steps) overall yields, respectively. The exceptionally high stereoselectivity of the dimethyldioxirane oxidation of trans-dihydrodiol having the quasi-diaxially disposed hydroxyl groups is particularly noteworthy.
