Abstract
The invention comprises compounds of the formula: <FORM:0918726/IV (b)/1> in which the double bond(s) containing a broken line may be fully hydrogenated and n is 1 to 4 inclusive, and a process for the preparation thereof by condensing 2,3-dimethoxy-5-methyl-benzohydroquinone-(1,4) or a 4-acyl derivative thereof with a tertiary alcohol of the formula: <FORM:0918726/IV (b)/2> or a primary alcohol obtained from this tertiary alcohol by allyl rearrangement or with an esterification product and, if necessary, hydrolysing the condensation product. The condensation may be effected in the presence of an acid condensing agent, e.g. zinc chloride in ether with the addition of acetic acid. Hydrolysis of the 4-acyl group may be effected with alkali. The Provisional Specification also discloses a process in which a compound having the second of the above formulae wherein n is 0 or 6-9, is employed.
