(R)-2-pentylcyclopentanone can be synthesized by the asymmetric hydrolysis of enol esters, catalyzed by immobilized candida antarctica (novozyme 435) lipase. Different acid moieties influence the stereoselectivity of lipase. Enol esters can be prepared fr

A protocol for effecting a rapid Saegusa-type oxidation of enol acetates is reported. This new method relies on the in situ elimination of an α-bromo intermediate to generate α,β-unsaturated ketones using copper(II) bromide. The methodology developed was applied to a range of substrates including a cyclohexanone, which could be directly converted to the corresponding phenol derivative. A catalytic system in which a non-masked ketone was successfully oxidised using substoichiometric CuBr2 was also developed as a proof of principle.
