Trifluoromethanesulfonic acid catalyzed isomerization of kineticenol derivatives to the thermodynamicallyfavoredisomers was developed. Under the present conditions, kineticenolphosphates, enol acetates and benzoates, and enol sulfonates were smoothly isomerized to produce the corresponding thermodynamicallyfavoredisomers in good to excellent yields.
