Abstract

Previous attempts to prepare the methoxy acid (I, R= CH3, R'= H) by catalytic reduction of the corresponding aromatic acid with platinum catalyst have been unsuccessful. In numerous other investigations the catalytic reduction of phenolic acids has been reported to give low yields of hydroxycyclohexane acids due to side reactions. Low pressure hydrogenation, particularly in acid medium, causes considerable hydrogenolysis of the ...
