Abstract

317,194. Boot's Pure Drug Co., Ltd., and Marshall, J. July 6, 1928. Acyl- and alkyl-phenols. - Acyl derivatives of monoalkyl ethers of catechol are made by treating aliphatic esters of the said monoalkyl ethers with aluminium chloride, two molecular proportions of the latter being employed to one of ester. The esters may be formed during the reaction by adding a fatty acid chloride to the monoalkyl ether. The aeyl group takes up the para-position to the hydroxyl group. In examples, 4-propionylguaiacol is obtained from guaiacol propionate, 4 - butylguaiacol from guaiacol butyrate, and 4-caproylguaiacol from guaiacol and caproyl chloride, nitrobenzene being employed as a solvent. The acyl groups may be reduced to alkyl groups, for example, by the Clemmensen process with amalgamated zinc and hydrochloric acid. The products are of therapeutic value.
