2-(2-Hydroxy-3-oxobutyl)-3,3-dimethylcyclopropanecarbaldehyde and certain derivatives thereof, such as 1-[2-(2,2-dihalovinyl)-3,3-dimethylcyclopropyl]-3-oxo-2-butyl acetate, are useful intermediates for the preparation of dihalovinyl-type pyrethroid esters.
摘要:
2-(2,2-Dimethoxyethyl-3,3-dimethylcyclopropanecarbaldehyde and 2-[2-(2,2-dihalovinyl)-3,3-dimethylcyclopropyl]ethanal dimethyl acetals are new pyrethroid intermediates. They are prepared from 2-(2-hydroxymethyl-3,3-dimethylcyclopropyl)ethanal dimethyl acetal.
摘要:
Process for the preparation of perfluorocarboxylic acids of the formula RF—COOH, salts thereof and esters thereof from perfluoroalkyl iodides of the formula RF′—I, in which RF and RF′ are cyclic, branched or linear, saturated or unsaturated perfluoroalkyl radicals, by activating the perfluoroalkyl iodides in the presence of oxygen and in organic solvents.
摘要:
New odoriferous compounds, particularly the compounds having the following formula: ##STR1## wherein R is an aliphatic residue having the formula ##STR2## wherein R.sup.1 is a C.sub.1-4 alkyl, C.sub.1-4 alkylidene or C.sub.2-4 alkenyl, the sum of the carbon atoms being in those residues from 2 to 5, m and n being equal to zero or 1, p being 1, 2 or 3 and the dotted lines representing one or two optional double bonds. The invention also relates to a method for the preparation of new di-ketones I: as well as the use of I as odoriferous compounds in odoriferous compositions, which are characterized by a certain proportion of compounds having the formula I.
摘要:
Preparation of novel alkyl 2,2-dihalovinylcyclopropylacetates (intermediates in the preparation of insecticides) by reaction of a phosphine with a compound generating a dihalocarbene and reaction of the product resulting therefrom with an alkyl formylcyclopropylacetate, both reactions being carried out in a solvent.
摘要:
A chloride channel opener, especially a prostaglandin compound, is used for the treatment of functional gastrointestinal disorders. The prostaglandin compound can be, for example, a 13,14-dihydro-15-keto-16,16-difluoro-prostaglandin E1 compound or 13,14-dihydro-15-keto-16,16-difluoro-18-methyl-prostaglandin E1 compound. The functional gastrointestinal disorders can be, for example, irritable bowel syndrome and/or functional dyspepsia. The treatment can include, for example, systemic administration 1-4 times per day or continuous administration of the compound in an amount of 0.01-100 μg per day.
