摘要:
A novel compound of 2-[para-(2-substituted or unsubstituted-3,3,3-trifluoropropyl)phenyl]propionic acid or a salt thereof which has a specific pharmacological activity and a pharmaceutical composition comprising the novel compound as an active ingredient are disclosed.
摘要:
A manufacturing method is described for the preparation of optically active 1-aromatic-group-substituted-1-alkanones characterized in that an optically active alkane acid halide is allowed to react with an aromatic compound in the presence of a Lewis acid. The optically active 1-aromatic-group-substituted-1-alkanones are useful intermediates in the preparation of optically active alpha-arylalkanoic acids, which are useful as pharmaceutical, e.g. anti-inflammatory, analgesic and anti-pyretic, agents and as insecticidal agents.
摘要:
Compounds of formula I wherein R.sup.1 and R.sup.2 are each selected from halomethyl and halo and R is nitro, cyano, lower alkoxycarbonyl, lower alkylcarbonyl, or di- or trifluoromethyl, and n has a value of zero to four, and compositions comprising them are useful as insecticides in agriculture, horticulture and other outlets. They may optionally be combined with other pesticides and/or synergists. The compounds may be prepared by conventional esterification processes from the corresponding acids and appropriately substituted benzyl alcohols or halides, some of which are novel. ##STR1##
摘要:
A process for the acylation of halo- or trihalomethylbenzenes, wherein a halo- or trihalomethylbenzene is reacted with a carboxylic acid, a precursor or a derivative thereof in the presence of boron trifluoride in an amount such that the absolute pressure of the boron trifluoride within the reaction vessel exceeds 1 bar, and in the presence of hydrofluoric acid as a solvent. The resultant products are useful as intermediates in the synthesis of compounds having a phytosanitary (e.g., herbicidal) or pharmaceutical activity.
