| titleOfInvention | Process for the preparation of 5-substituted resorcinols and related intermediates |
| abstract | According to the present invention, 5-substituted resorcinols of the formula I ##STR1## wherein R 1 represents a hydrocarbon radical, optionally unsubstituted or substituted by inert substituents, are prepared by reacting a carboxylic acid ester of the formula II n n R.sub.1 --C.tbd.C--CO--O--R.sub.2 (II) n n wherein R 2 represents a non-aromatically bound lower hydrocarbon radical, in the presence of an alkaline condensation agent, with a diester of 3-oxoglutaric acid of the formula III n n R.sub.3 --O--CO--CH.sub.2 --CO--CH.sub.2 --CO--O--R.sub.4 (III) n n wherein R 3 and R 4 represent non-aromatically bound lower hydrocarbon radicals; hydrolyzing the resulting dihydroxyisophthalic acid acid ester of the formula IV ##STR2## and decarboxylating the hydrolyzed product, a specific embodiment is the preparation of 5-pentylresorcinol. |
