标 题 :Method of synthesis of retinoic acid
发明人:DELUCA HECTOR F; TADIKONDA PRAVEEN K
权利人:WISCONSIN ALUMNI RES FOUND
摘要:A method of synthesizing 9-cis-retinoic acid, all-trans-retinoic acid or 9-nor-retinoic acid is disclosed. The method comprises the steps of adding a Grignard reagent of ##STR1## to 2,2,6 trimethyl cyclohexanone is disclosed. R is a methyl group or H and the CH 2 --OH group is in either the cis or trans orientation relative to the HC.tbd.C- group. The resulting product is converted into retinoic acid. In the preferable form of the present invention, a tritium-labelled retinoic acid is synthesized, wherein the labelling is at the C 20 position. A preparation of tritium-labelled 9-cis-retinoic acid with a specific activity of greater than 65 Ci/mmol is also enclosed. In a most preferred embodiment, the specific activity is greater than 75 Ci/mmol.

摘要: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 1 and Z 2 combinedly represent â•?O, â•?CH--COOH,â•?CH--COOR 1 , â•?CH--CN, â•?C(CN)COOR 2 , â•?CH--CO--NH 2 , â•?CH--CO--N(R 3 ) (R 4 ), â•?CH--CO--NHR 5 , â•?CH--CH 2 --N(R 3 ) (R 4 ), â•?CH--CH 2 --NHR 5 or â•?CH--CHO or Z 1 is a hydrogen atom and Z 2 is --CH 2 COOH, --CH 2 COOR 6 , --CH(CN)COOR 2 , --CH 2 CN, --CH 2 --CO--NH 2 , --CHâ•?CH--N(R 3 ) (R 4 ) or --CH 2 --CHâ•?N--R 5 , R 1 , R 2 and R 6 each being a lower alkyl group, R 3 and R 4 each independently being a lower-alkyl, cycloalkyl, aryl or aralkyl group or R 3 and R 4 combinedly representing an alkylene group containing 2-5 carbon atoms, and R 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 ue of an expensive C 5 chain extender.
