Oxidation of methyl dimorphecolate (1) to methyl 9-oxo-10,12-E,E-octadecadienoate (2) has been studied, using Oppenauer conditions. Acetone and cyclohexanone have been used as oxidizing ketones. Combination of cyclohexanone with inert solvents has been performed to minimize the side reactions: degradation of the aluminum alkoxide catalyst and transesterification of the desired product (2). The optimal procedure is reported on 25 g scale using cyclohexanone (1.5 eq) and aluminum t-butoxide (0.2 eq) in hexane at 50 degrees C (30 min).
