摘要:
A process for asymmetric synthesis of optically active 2-alkanoyl-1,2,3,4-tetrahydro-2-naphthol compounds of the formula: ##STR1## from L-proline or its ester and the following carboxylic acid of the formula: ##STR2## or its reactive derivative through the following intermediary compounds in order: ##STR3##
摘要:
Compounds of the formula ##STR1## wherein R is hydrogen or methyl; R.sup.1 is hydrogen, C.sub.1 to C.sub.8 linear or branched alkyl or C.sub.1 to C.sub.8 linear or branched alkanoyl; X is oxygen or sulfur; R.sup.2 is selected from the group hydrogen, C.sub.1 to C.sub.18 linear or branched alkyl and the radicals --(CH.sub.2).sub.n --NR.sup.3 R.sup.4, --CH.sub.2 --CH(OH)--CH.sub.2 --OH or a ketal thereof formed from the aldehyde or ketone R.sup.5 R.sup.6 CO, wherein R.sup.3 and R.sup.4 are each independently C.sub.1 to C.sub.6 linear or branched alkyl or R.sup.3 and R.sup.4 taken together with the nitrogen atom of the first radical are attached to form a 5- or 6-membered heterocyclic ring, R.sup.5 and R.sup.6 are each independently hydrogen, C.sub.1 to C.sub.6 linear or branched alkyl, phenyl or benzyl or R.sup.5 and R.sup.6 taken together represent an alkylene bridge of from 4 to 6 carbon atoms; n is an integer of from 2 to 4; and the dotted line represents an optional double bond; and the pharmaceutically acceptable salts thereof. The compounds have anti-inflammatory, analgesic and anti-pyretic activities and, accordingly, are useful in the treatment of inflammation, pain and/or pyrexia.
摘要:
Aromatic tetracarboxylic acids can be prepared by effecting reaction between a 4-nitro-N-alkylphthalimide with an aromatic dihydroxy compound in the presence of potassium carbonate as a catalyst and using dimethyl sulfoxide as a solvent.
摘要:
1-Oxo-2,2-disubstituted-5-indanyloxy(or thio)alkanoic acids and their salt, ester, anhydride, amide and 5-tetrazolyl derivatives are disclosed. The products display a dual pharmaceutical utility in that they exhibit diuretic, saluretic and uricosuric activity. The acid products are prepared by treating a 2,2-disubstituted-5-hydroxy(or mercapto)-1-indanone with an haloalkanoic acid or ester thereof and, if the ester is employed, hydrolyzing the ester.
摘要:
This invention is a group of 8-beta, 12-alpha-PG.sub.2 (prostaglandin-type) analogs having variable chain length, or methyl or phenyl substitution in the hydroxy-substituted side-chain, and processes for making them. These compounds are useful for a variety of pharmacological purposes, including anti-ulcer, inhibition of platelet aggregation, increase of nasal patency, and labor inducement at term.
