Abstract
Process for prepg. specific stereoisomers of farnesylacetic aced or its esters of formula (I): CH3. C(CH3)=CH.CH2CH2. C(CH3)DELTA8=CH. CH2CH2. C(CH3)DELTA4= CHCH2CH2COOR2 (I) (R2 = H, 1-6C alkyl, 3-6C cycloalkyl, 2-6C alkenyl or 3-6C cycloalkenyl)comprises rectifying a mixt. of (i) DELTA4,8-cis and DELTA4-trans-DELTA-cis (I); (ii) DELTA4,8-trans (I) or (III) all 4 isomers to recovery from mixts. (i) and (ii) both components and from (iii) the DELTA4,8-cis isomers. Similar processes for separg. DELTA6-cis and DELTA6-trans isomers of nerolidol (II) and DELTA5-cis and DELTA5-trans geranylacetone (III) are also new. (I) are anti-ulcer agents (for which purpose individual isomers are pref), perfumes and aroma agents. (II) and (III) are intermediates for (I), perfumes and cpds. with juvenile hormone activity; (II) is also used to make isophytol a starting material for Vitamin E. Recovery of individual isomers is almost quantitative.
