Synthesis of anti- and syn-Diol Epoxides of trans-4,5-Dihydro-4,5-dihydroxybenzofluoranthene and trans-9,10-Dihydro-9,10-dihydroxybenzofluoranthene

The preparation of diastereomeric anti- and syn-epoxides of benzofluoranthene (BjF) 4,5- and 9,10-dihydrodiols is described.The anti-diol epoxides were prepared from the corresponding dihydrodiols by epoxidation with m-chloroperbenzoic acid.The isomeri
