Abstract:
The present disclosure describes processes for the epimerization of a cyclohexene comprising the steps of providing to a reactor a first isomer of a 1-(2-alkyl-3-cyclohexen-1-yl)-alkanone compound according to Formula I wherein R1 ad R2 are each independently C1-C4 alkyl, and R3, R4, R5, R6, R7, and R8 are each independently selected from the group consisting of H and C1-C4 alkyl; and epimerizing the first isomer of the 1-(2-alkyl-3-cyclohexen-1-yl)-alkanone with a metal alkoxide base to form a second isomer of the 1-(2-alkyl-3-cyclohexen-1-yl)-alkanone.
