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:(−) 3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan (ambrox) is a strong aromatic compound used widely in a variety of perfumery applications and is highly prized for its musky odor. We report novel polar metabolites of (−)3a,6,6,9a-tetramethylperhydronaphtho[2,1-b]furan prepared by a novel process of microbial fermentation using a fungi, Fusarium lini , of unique structures that would be difficult to predict opening up the possibilities of their chemical synthesis. The polar metabolites discovered have stronger aromatic characteristics and offer a new highly prized odiferous characteristic quite different from that of the parent compound and thus can be used in the preparation of perfumes, odor-masking and other odor-management applications.
