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 Rad Rare each independently C-Calkyl, and R, R, R, R, R, and Rare each independently selected from the group consisting of H and C-Calkyl; 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.

Processes for epimerizing cyclohexenyl ketones with subsequent aldol condensation to produce fragrance compounds

The present disclosure describes processes for producing cyclohexenes using Lewis acidic ionic liquids comprising the steps of providing to a reactor an &#x3b1;,&#x3b2;-unsaturated carbonyl dienophile, providing to the reactor a 1,3-diene, providing a Lewis acidic ionic liquid to the reactor; and reacting the &#x3b1;,&#x3b2;-unsaturated carbonyl dienophile with 1,3-diene to form a substituted cyclohexene product. The &#x3b1;,&#x3b2;-unsaturated carbonyl dienophile can be mesityl oxide, the 1,3-diene can be piperylene; and the Lewis acidic ionic liquid can be AlCl:[Cmim]Cl; AlCl:[Cmim]Cl; or mixtures thereof.
