    • There are provided polyprenyl compounds of the formula ##STR1## wherein ##STR2## represent a trans-isoprene unit and a cis-isoprene unit, respectively, n is an integer of 11-19, Z.sup.1 and Z.sup.2 combinedly represent .dbd.O, .dbd.CH--COOH,.dbd.CH--COOR.sup.1, .dbd.CH--CN, .dbd.C(CN)COOR.sup.2, .dbd.CH--CO--NH.sub.2, .dbd.CH--CO--N(R.sup.3) (R.sup.4), .dbd.CH--CO--NHR.sup.5, .dbd.CH--CH.sub.2 --N(R.sup.3) (R.sup.4), .dbd.CH--CH.sub.2 --NHR.sup.5 or .dbd.CH--CHO or Z.sup.1 is a hydrogen atom and Z.sup.2 is --CH.sub.2 COOH, --CH.sub.2 COOR.sup.6, --CH(CN)COOR.sup.2, --CH.sub.2 CN, --CH.sub.2 --CO--NH.sub.2, --CH.dbd.CH--N(R.sup.3) (R.sup.4) or --CH.sub.2 --CH.dbd.N--R.sup.5, R.sup.1, R.sup.2 and R.sup.6 each being a lower alkyl group, R.sup.3 and R.sup.4 each independently being a lower-alkyl, cycloalkyl, aryl or aralkyl group or R.sup.3 and R.sup.4 combinedly representing an alkylene group containing 2-5 carbon atoms, and R.sup.5 being a lower-alkyl, cycloalkyl, aryl or aralkyl group. These polyprenyl compounds can be synthesized starting with a polyprenol obtainable from leaves of a plant such as Ginkgo biloba or Cedrus deodara by extraction and as necessary followed by hydrolysis, or a reactive derivative thereof. The polyprenyl compounds are useful as intermediates for the synthesis of dolichol without the use of an expensive C.sub.5 chain extender.
    • 提供下式的聚异戊二烯基化合物:其中,“IMAGE”分别代表异戊二烯单元和顺式异戊二烯单元,n为11-19的整数,Z1和Z2组合表示 = CH 2 COOR 1 = CH-COOR 1 = CH-CN = C(CN)COOR 2 = CH-CO-NH 2 = CH-CO-N(R3)(R4) NHR 5,= CH-CH 2 -N(R 3)(R 4),= CH-CH 2 -NHR 5或= CH-CHO或Z 1是氢原子,Z 2是-CH 2 COOH,-CH 2 COOR 6,-CH(CN)COOR 2,-CH 2 CN ,-CH 2 -CO-NH 2,-CH = CH-N(R 3)(R 4)或-CH 2 -CH = N-R 5,R 1,R 2和R 6各自为低级烷基,R 3和R 4各自独立地为低级 - 烷基,环烷基,芳基或芳烷基或R3和R4组合表示含2-5个碳原子的亚烷基,R5为低级烷基,环烷基,芳基或芳烷基。 这些聚异戊二烯基化合物可以从通过提取从植物如银杏叶或Cedrus deodara的叶获得的聚异戊二烯开始合成,并且根据需要随后进行水解或其活性衍生物合成。 聚异戊二烯基化合物可用作合成Dolichol而不使用昂贵的C5扩链剂的中间体。
