Aliphatic vs. aromatric C–H bond activation of phenylcyclohexane catalysed by cytochrome P450cam

Abstract
Catalytic hydroxylation of phenylcyclohexane 1 by wild-type and the Y96A and Y96F mutant forms of cytochrome P450cam occurs only at the 3- and 4-positions on the cyclohexane ring, giving cis-3-phenylcyclohexanol 2, cis-4-phenylcyclohexanol 3 and trans-4-phenylcyclohexanol 4.
