    摘要: Pure polyunsaturated fatty acid amides and their derivatives. These synthcally produced compounds are able to mimic naturally occuring anandamides in the brain and bind the cannabinoid receptor. The compounds exhibit physiological activity and are useful as active ingredients in pharmaceutical compositions for the treatment of inflammation, migraines, spasticity activity, glaucoma, multiple sclerosis. The active compounds can be provided in isotope-tagged form.

    摘要: In the continuous process described for the preparation of dimethyldiallylammonium chloride by reaction, with stirring, of dimethylamine, allyl chloride and alkali metal hydroxide which is dissolved in water, the reaction is carried out in at least two stirred vessels arranged in the form of a cascade. Dimethylamine and allyl chloride in the stoichiometric amount in each case and only 60 to 95 mol % of the stoichiometrically necessary amount of alkali metal hydroxide are fed to the first stirred vessel and conducted through the vessel at a temperature of 20.degree. to 70.degree. C. with a residence time such that the product leaving the vessel and flowing to the further vessels still contains at most 10 mol % of free amine, mol percentages being related to the molar amount of dimethylamine employed; the alkali metal hydroxide lacking in the first stirred vessel compared to the stoichiometric amount is fed continuously to the further stirred vessels mentioned and in these vessels, at a temperature of 20.degree. to 70.degree. C., a residence time is set such that the product leaving the vessel still contains at most 2 mol % of free amine in each case. The desired dimethyldiallylammonium chloride is obtained from the product leaving the stirred vessel cascade.

    摘要: A one-pot process for the preparation of functional alkoxyamines of the general formula (I), 1 is disclosed. The process entails (1) reacting an oxidizing agent with a sterically hindered secondary amine to produce an aqueous phase and a nitroxyl radical (2) removing the aqueous phase and adding to the nitroxyl radical one or more vinyl monomer(s) conforming to a formula and a system which produces free radicals. Also disclosed is a process of polymerizing monomers using the functional alkoxyamine.
