Abstract: Compounds of formula: ##STR1## in which R and R' denote an alkyl radical having 1 to 7 carbon atoms; R.sub.1 denotes hydrogen or an alkyl radical having 1 to 7 carbon atoms; and R.sub.2 and R.sub.3 denote, separately, an alkyl radical having 1 to 7 carbon atoms or a phenyl radical, or, together with the carbon atom to which they are attached, a cycloalkyl radical having at most 7 carbon atoms; n may assume the values 2 or 3; and their pharmaceutically acceptable salts.Application as a cardiovascular medicinal product.

Abstract: N,N-dimethyl-N'-benzoyl-N'-(2,3-dihydrobenzofuran-2-ylmethyl)1,3-propanedia mine of formula: ##STR1## and its pharmaceutically acceptable salts, in racemic form or in the form of enantiomers, which compounds have anti-arrhythmic properties.

Abstract: The invention relates to compounds of the formula: ##STR1## and pharmaceutically acceptable salts thereof, in which X represents either --CH.dbd. or --N.dbd., R.sub.1 represents an alkyl radical having 1 to 5 carbon atoms, R.sub.2 represents hydrogen and R.sub.3 is an alkyl radical having 1 to 5 carbon atoms, or R.sub.2 and R.sub.3, together with the nitrogen atom to which they are bonded, represent a heterocyclic radical, such as pyrrolidinyl, morpholino, 4-phenyl-piperazinyl, in which the phenyl radical can carry one or more substituents, such as a halogen atom, an alkyl or alkoxy radical having 1 to 5 carbon atoms or the trifluoromethyl radical, or represents 4-(2-pyrimidinyl)-piperazinyl, having anti-bronchoconstrictory properties.

Abstract: The invention is dealing with antispasmodic compounds of the formula I ##STR1## in which R.sub.1 denotes H, halogen or a linear or branched C.sub.1 to C.sub.3 alkoxy or alkyl group, R.sub.2, R.sub.3 and R.sub.4 separately denote a linear or branched C.sub.1 to C.sub.4 alkyl group or R.sub.2 and R.sub.3 together with the nitrogen atom to which they are bound form a saturated heterocyclic radical, Z denotes a linear or branched C.sub.1 to C.sub.6 alkylene group and X.sup.- denotes an anion, preferably a halogen ion,and is dealing with intermediates in the preparation of the compounds of formula I.
