The cytochrome P450 monooxygenase CYP101B1 from Novosphingobium aromaticivorans selectively hydroxylated methylene C-H bonds in cycloalkyl rings. Cycloketones and cycloalkyl esters containing C6, C8, C10 and C12 rings were oxidised with high selectively on the opposite side of the ring to the carbonyl substituent. Cyclodecanone was oxidised to oxabicycloundecanol derivatives in equilibrium with the hydroxycyclodecanones.

The elimination of lithium, magnesium and aluminium enolates of isobutyrates of medium ring cyclanols occurs in a syn fashion.A set of experimental procedures is presented.This elimination seems to be restricted to strained systems.The stereochemistry has been determined on stereospecifically deuterated cyclooctanol isobutyrates.The primary isotope effect kH/k2 was 3.0 +/- 0.1 and the secondary 1.1.The name β'β elimination is proposed for this syn elimination and related elimination.
