Process for the production of dien-1-ols, 9-hydroxydodec-10-enyl-1-tert.butyl ether, and its use as an intermediate in the synthesis of 8,10-dodecane dienol
Process for the production of dien-1-ols, 9-hydroxydodec-10-enyl-1-tert.butyl ether, and its use as an intermediate in the synthesis of 8,10-dodecane dienol
Dien-1-ols of the general formula I IMAGE (I) where the radicals R1 to R7 are identical to or different from one another and each is hydrogen or straight-chain or branched alkyl or 1-12 carbon atoms and n is 1-14, are prepared by dehydrating a hydroxylalkenyl tert-butyl ether of the formula II IMAGE (II) in the presence of an acidic catalyst at elevated tempertures and essentially at the same time splitting off the tert-butyl protective group, as is 9-hydroxydodec-10-enyl 1-tert-butyl ether which is useful as an intermediate for synthesizing 8,10-dodecadienol.
