  • Stereoselective Formation of (E)-β-Alkoxy Acrylates from Fischer Carbene Complexes and Chelated Amino Acid Ester Enolates
    作者:Uli Kazmaier、Rupsha Chaudhuri
    DOI:10.1055/s-0033-1340496
    日期:——
    Chelated amino acid ester enolates react with alkyl Fischer carbene complexes via nucleophilic attack on the electrophilic carbene center. Subsequent elimination of the metal fragment and trifluoroacetamide results in the formation of β-alkoxy-α,β-­unsaturated esters in a highly E -stereoselective fashion.

    The syntheses of five metabolites of the antiinflammatory drug etodolac (1,8-diethyl-1,3,4,9-tetrahydropyrano-[3,4-b]indole-1-acetic acid) are described, viz. 6-hydroxyetodolac, N-methyletodolac, 4-ureidoetodolac, 8-(1'-hydroxy)etodolac, and 4-oxoetodolac. These syntheses were used to confirm the identities of the metabolites. The metabolites themselves, as well as the previously reported metabolite

  • Amino acid esters, process for the preparation thereof and use thereof
    申请人:Dr. Willmar Schwabe GmbH & Co.

    Novel esters of amino acids are proposed of which the alcoholic components are formed from threo-4-alkoxy-5-arylhydroxymethyl-2(5H)-furanones. These esters may be present in the form of racemates, pure diastereomers or enantiomers or in the form of diastereomer or enantiomer mixtures. The compounds are anticonvulsive and antiepileptic and due to their good water solubility are easier to administer and more readily absorbable than known anti-convulsives and antiepileptics. A novel process is also disclosed which leads stereoselectively to the diastereomers or the enantiomers or mixtures thereof. The invention further relates to the use of the novel amino acid esters as pharmaceutical preparations and in the production of pharmaceutical preparations.
    提出了一种新的氨基酸酯类化合物,其中醇性组分由threo-4-烷氧基-5-芳基羟甲基-2(5H)-呋喃酮形成。这些酯类化合物可以以外消旋体、纯对映异构体或对映体的形式存在,也可以以对映异构体或对映体混合物的形式存在。这些化合物具有抗惊厥和抗癫痫作用,并且由于其良好的水溶性,比已知的抗惊厥和抗癫痫药物更容易给药和更容易被吸收。还公开了一种新的过程,可以立体选择性地产生这些化合物的对映异构体或对映体或它们的混合物。该发明还涉及将这些新型氨基酸酯类化合物用作药物制剂以及在药物制剂的生产中的用途。

    The present invention provides 5-arylalkyl-4-alkoxy-2(5H)-furanones of the formula: ##STR1## wherein the oxygen atoms on C-5 and C-.alpha., relative to one another, are in the threo-position, with the exclusion of those compounds of the formula (I) wherein R.sup.2 is H or CH.sub.3 when n=0 or 2, R.sup.o =H, R.sup.1 =CH.sub.3, R.sup.3 =H and R.sup.4 =H. The present invention also provides processes for their preparation, as well as new 3-alkoxy-5-(subst.)-phenyl-2(E), 4(E)-pentadienoates as reactive intermediates for the preparation of the new furanone derivatives. The new furanone derivatives of the threo series are active as anticonvulsives/anti-epileptics. Therefore, the present invention also provides medicaments which contain these new furanone derivatives, as well as known furanones, the anticonvulsive/anti-epileptic effectiveness of which has been found for the first time.
