Abstract

Novel acyclic terpene compounds useful as intermediates for producing sarcophytol A which have an anti-carcinogenic promotor activity and anti-tumor activity, which compounds are shown by the following general formula (I): ##STR1## [wherein R.sup.1 is a hydrogen atom, 1-alkoxyalkyl group, tetrahydrofuryl group, tetrahydropyranyl group or acyl group; R.sup.2 is a group of formula: --CHO, --CH.sub.2 OR.sup.3 or ##STR2## (wherein R.sup.3 is a hydrogen atom, 1-alkoxyalkyl group, tetrahydrofuryl group, tetrahydropyranyl group or acyl group; and R.sup.4 is C.sub.1 to C.sub.4 alkyl group) with the proviso that R.sup.1 and R.sup.3 do not represent the same substituents simultaneously; when R.sup.1 is a hydrogen atom, R.sup.3 is not acetyl group or tetrahydropyranyl group; and when R.sup.2 is a group of formula: ##STR3## R.sup.1 is not a hydrogen atom).
