Preparing an aryl aldehyde/ketone from a cyclic aryl epoxide, useful e.g. as a flavoring agent, where process takes place in a cell-free reaction mixture comprising styrene-oxide isomerase in an aqueous solution and the aryl epoxide

Enzymatic synthesis of aryl aldehyde (I) or aryl ketone (II) from mono- or bi-cyclic aryl epoxide, is claimed, where the enzymatic catalyzed synthesis takes place in a cell-free reaction mixture comprising styrene-oxide isomerase in an aqueous solution and a mono- or bi-cyclic aryl epoxide. An indep...
