摘要:
Minor tranquilizers preparable by known processes are represented by the following structural formula I: ##STR1## wherein R.sup.o is hydrogen, halo of atomic weight of from 18 to 80, i.e. fluoro, chloro or bromo or alkyl of 1 to 3 carbon atoms,R is halo of atomic weight of from 18 to 80, alkyl of 1 to 4 carbon atoms or trifluoromethyl,R' is alkenyl of 3 to 6 carbon atoms, alkynyl of 3 to 6 carbon atoms, cycloalkyl of 3 to 8 carbon atoms, norbornyl, alkyl of 1 to 3 carbon atoms substituted by cycloalkyl of 3 to 7 carbon atoms or --CH.sub.2 (F.sub.x ALK) wherein x is 1 to 3 and ALK is alkyl of 1 to 4 carbon atoms,R.sub.1, R.sub.2, and R.sub.3 are independently hydrogen or alkyl of 1 or 2 carbon atoms, andn is 0 or 1.
摘要:
Hydroxyalkyl and aryl or heterocyclic substituted-4,5-dihydropyridazin(2H)-3-ones and diazabicyclo-ene-ones e.g., 6-(p-chlorophenyl)-2-(2-hydroxybutyl)-4,5-dihydropyridazin(2H)-3-one are prepared by condensing 1-hydrazino-2-alkanols with aryl or heterocyclic-.gamma.-keto acids and are useful as central nervous system depressants.
摘要:
Alkanoyl substituted benzoic acids and esters, e.g., p-pivaloyl ethyl benzoate, are prepared by oxidizing alkanoyl substituted toluene and reacting with lower alkanols and are useful as hypolipidemic, anti-obesity, and anti-diabetic agents.
摘要:
Disclosed are compounds of the class of 1-alkyl-4-phenyl and 4-(2-thienyl)-6,7-methylenedioxy-2(1H)-quinazolinones and quinazolinthiones, including the 3,4-dihydro derivatives thereof, useful as pharmaceutical agents, e.g. as anti-inflammatory agents. Such compounds, e.g. 1-isopropyl-4-phenyl-6,7-methylenedioxy-2(1H)-quinazolinones and 1-isopropyl-4-phenyl-6,7-methylenedioxy-2(1H)-quinazolinthiones, may be prepared by reacting the corresponding N-alkyl-N-(3,4-methylenedioxyphenyl)urea or thiourea with an aromatic aldehyde, e.g. benzaldehyde, in the presence of an acid at elevated temperatures to obtain the 3,4-dihydro-2(1H)-quinazolinones or 3,4-dihydro-2(1H)-quinazolinthiones which may then be oxidized to the corresponding 3,4-unsaturated compounds.
摘要:
Substituted 1,2-dihydrobenz[f]isoquinolines, e.g., 4-(p-chlorophenyl)-1,2-dihydrobenz[f]isoquinoline, are prepared by cyclizing N-substituted-.alpha.-naphthylethylamines and are useful as non-estrogenic antifertility agents.
摘要:
10-(2-substituted-aminoethyl)-10,11-dihydro-5-methyl-2 or 3, 7 or 8-substituted or unsubstituted-5H-dibenzo[a,d]cycloheptenes, e.g., 10-(2-dimethylaminoethyl)-10,11-dihydro-5-methyl-5H-dibenzo[a,d]cycloheptene, are prepared by hydrogenating a corresponding 10-(2-dimethyl-aminoethyl)-10,11-dihydro-5-methylene-2 or 3, 7 or 8-substituted or unsubstituted-5H-dibenzo[a,d]cycloheptenes and are useful as anti-depressants.
摘要:
Acyl substituted or unsubstituted benzyl ethers, e.g., p-(phenoxymethyl)pivalophenone, are prepared by reacting a corresponding .alpha.-bromo-p-pivaloyl toluene with a corresponding phenol and are useful as hypolipidemic agents.
摘要:
5-hydroxy-5-substituted phenyl-pyrrolidones and piperidinones, 3.g., 5-hydroxy-1-methyl-5-(m-trifluoromethylphenyl)pyrrolidone, are useful as sedative-hypnotic agents and minor tranquilizers.
摘要:
Disclosed is single phase multi-stage process for preparation of 1-aryl-4,5-dihalo-pyridazones-6 involving the diazotization of an amino aryl compound, e.g. aniline, followed by reduction with sulfurous acid to obtain the corresponding aryl hydrazine which is then reacted at elevated temperatures with a mucohalic acid to obtain the 1-aryl-4,5-dihalo-pyridazone-6.
