13) of benzo[b]naphtho[1,2-d]furan 8, and benzo[b]naphtho[1,2-d]thiophene 9, to yield the corresponding enantiopure hexahydro cis-diols 14 and 15. A novel tandem cis-dihydroxylation and bis-desaturation of the tetrahydro-substrate, tetrahydrobenzo[b]naphtho[1,2-d]thiophene 13, catalysed by biphenyl dioxygenase, was found to yield the fjord-region cis-dihydrodiol 17 of benzo[b]naphtho[1,2-d]thiophene
