Novel polyprenyl compounds have the general formula: ##STR1## represents a cis-isoprene unit, n is an integer of 11-19, Z.sup.1 is --CH.sub.2 OH or a functional precursor thereof, and either one of R.sup.1 and R.sup.2 is a hydrogen atom and the other is --S(O).sub.m R.sup.3 in which m is an integer of 0 (zero), 1 or 2 and R.sup.3 is a phenyl, naphthyl, pyridyl or thiazolinyl group or such group substituted with at least one lower alkyl and/or halogen substituent. The topic novel polyprenyl compounds can be synthesized from derivatives of the polyprenol which is obtainable from leaves of Ginkgo biloba or Cedrus deodara, among others, by extraction, if necessary followed by hydrolytic treatment. The novel polyprenyl compounds can be converted to mammalian dolichols or precursors thereof by reductive elimination of the --S(O).sub.m R.sup.3 group.
新型多萜化合物的通式为:##STR1##其中,表示顺式异戊二烯单元,n是11-19的整数,Z.sup.1是--CH.sub.2 OH或其它官能前体,而R.sup.1和R.sup.2中的一个是氢原子,另一个是--S(O).sub.m R.sup.3,其中m是0(零)、1或2的整数,R.sup.3是苯基、萘基、吡啶基或噻唑啉基或这些基团中至少有一个取代了至少一个较低的烷基和/或卤素取代基。这些新型多萜化合物可以从银杏叶或雪松等植物中提取多萜醇的衍生物,并在必要时进行水解处理而合成。这些新型多萜化合物可以通过还原消除--S(O).sub.m R.sup.3基团而转化为哺乳动物的长链醇或其前体。
