Asymmetric cis-dihydroxylation to yield diols 2A–2G and sequential benzylic monohydroxylation–cis-dihydroxylation to yield triols 4A–4G (trihydroxylation), occurred during biotransformation of a series of monosubstituted alkylbenzene substrates 1A–1G using toluene dioxygenase, a biocatalyst present in Pseudomonasputida UV4. Dioxygenase-catalysed cis-dihydroxylation of the R and S benzylic alcohol

Dioxygenase-catalysed trioxygenation of alkylphenylsulfides and alkyl benzenes yields enantiopure cis-dihydrodiol sulfoxides and triols respectively; naphthalene cis-dihydrodiol dehydrogenase-catalysed aromatisation of these diastereoisomers gives enantiopure catechols of either configuration.
