Compounds of the formula I ##STR1## in which R.sub.1 signifies an aryl, aralkyl or an aralkenyl group, the aryl radical of which can, in each case, be substituted one or more times by halogen, cyano, alkyl, trifluoromethyl, alkoxy, alkylthio, trifluoromethoxy, hydroxyl or carboxyl, m a whole number from 1 to 3, n a whole number from 1 to 5, R.sub.2 hydrogen, an alkyl, aralkyl or acyl group, Q a bond or an oxygen atom, R.sub.3 hydrogen or a lower alkyl radical which is possibly terminally substituted by carboxyl or by a hydroxyl group and R.sub.4 hydrogen, a lower alkyl group with 1-4 C-atoms, which is possibly terminally substituted by carboxyl or hydroxyl, a possibly substituted phenyl, heteroaryl, cycloalkyl or acyl group or a group ##STR2## in which R.sub.5 represents a straight-chained or branched alkyl chain with 1-4 C-atoms which is possibly terminally substituted by carboxyl, alkoxycarbonyl, aminocarbonyl, hydroxyl, mercapto, alkylthio or imidazolyl and Y a carboxyl, an alkoxycarbonyl, aminocarbonyl or cyano, formyl, hydroxymethyl, aminomethyl or ortho ester group, whereby R.sub.3 and R.sub.4 can also be component of a 5- or 6-membered saturated or unsaturated possibly substituted heterocycle with 1-4 heteroatoms which can be annellated with further ring compounds via one or more bonds, as well as their salts, esters and amides, processes for their preparation and medicaments with thromboxane-antagonistic action which contain these compounds.
