摘要:
The compounds are 1-aryl-1-lower alkyl-substituted-1-buten-3-ols, butan-3-ols, and acylation products thereof, e.g., (p-biphenylyl)-2-penten-4-ol and are useful as pharmaceuticals.
摘要:
The final products are compounds of the formula ##STR1## wherein (a) each of R.sup.1, R.sup.2 and R.sup.3 alkyl having from 1 to 22 carbon atoms; or(b) one or more is a phenyl or alkylphenyl type, n is from 3 to 20; andR is of an aralkyl-, phenyl-tryptophanyl- or benzocycloalkyl-type, eg D,L-5,5-dimethyl-5-sila-pentadecanoyl-1'-phenyl-2'-p-tolyl-ethylamide, are useful as antiatherosclerotic agents, and are prepared from corresponding carboxylic acids (or their derivatives).
摘要:
Disclosed are compounds which are 4-hydroxy-2-quinolinone-3-carboxylic acids and salts thereof, e.g., 1-allyl-6,7-dimethoxy-4-hydroxy-2-quinolinone-3-carboxylic acid, useful as anti-allergic agents, and prepared by hydrolysis of the corresponding carboxylic acid esters.
摘要:
Anti-allergic 4-hydroxy-3-nitro-pyrido[2,3-b]pyridines-2(1H)-ones are prepared by reacting a 3,4-dihydro-1,3-dioxo-1H-pyrido[2,3-d][1,3]oxazine (a 3-azaisatoic anhydride) with the carbanion resulting from the reaction of nitro acetic acid alkyl esters with a proton abstracting agent.
摘要:
An improved process for the preparation of optionally substituted 2,3-indolinediones which are useful as intermediates in the preparation of compounds having pharmacological activity which comprises reacting a 3,1-benzoxazine with an alkali or alkaline earth metal cyanide or a tetra-(C.sub.1-4) alkylammonium cyanide to obtain a 2-imino-3-indolinone, which is then subjected to hydrolysis.
摘要:
Textile materials containing at least 50% by weight triacetate fibers are dyed with disperse dyes in an aqueous dyebath containing an emulsifier and, as carrier, an aliphatic dicarboxylic acid diester having 6 to 24 carbon atoms, such as dibutyl maleate.
摘要:
Ketone derivatives of 4,5-dihydro-3(2H)-pyridazinones of the formula ##STR1## where R.sub.1 is halo having an atomic weight of from 19 to 36, andR.sub.2 is a branched chain lower alkyl having 3 to 4 carbon atomsare useful as central nervous system depressants, in particular, as muscle relaxants.
摘要:
The invention relates to novel, polymeric phosphate esters containing at least two orthophosphate groups bridged by a polyoxyalkylene radical, and to the use of said esters as emulsifiers, surfactants, dispersants and fiber finishing agents.
摘要:
Multicolored substrates, particularly nylon carpeting, are produced by applying combinations of a colorless reserving agent and an acid, direct or basic dye or mixture of dyes and fixing the reserving agent and the dye(s) simultaneously.
