Wild-type P450-BM3 is able to catalyze in a highly regio- and diastereoselective manner the oxidative hydroxylation of non-activated disubstituted cyclohexane derivatives lacking any functional groups, including cis- and trans-1,2-dimethylcyclohexane, cis- and trans-1,4-dimethylcyclohexane, and trans-1,4-methylisopropylcyclohexane. In all cases except chiral trans-1,2-dimethylcyclohexane as substrate, the single hydroxylation event at a methylene group induces desymmetrization with simultaneous creation of three centers of chirality. Certain mutants increase selectivity, setting the stage for future directed evolution work.

The analysis of aroma volatiles of parsley revealed the presence of two novel oxygenated p-mentha-1,3,8-tiene derivatives, the amounts of which increase during processing of plant material and deteriorate the typical fresh aroma.The two derivatives, which could be synthesized by means of a dye sensitized photooxygenation reaction, were identified as 1-methyl-4(methylethenyl)-2,3-dioxabicyclooct-5-ene and 4-methyl-7-(methylethenyl)-3,8-dioxatricyclo2-4>octane.Key Word Index - Petroselinum crispum; Umbelliferae; parsley; aroma volatiles; p-mentha-1,3,8-triene; dioxetane; 1-methyl-4-(methylethenyl)-2,3-dioxabicyclooct-5-ene; diepoxide; 4-methyl-7-(methylethenyl)-3,8-dioxatricyclo2-4>octane.
