  The invention relates to the use in medicine of 1-alkylimidazoles of formula in which A is a straight or branched, saturated or unsaturated acyclic hydrocarbon radical of from 1 to 3 carbon atoms; n is 0 or 1; and R is a cycloalkyl or cycloalkenyl radical of from 4 to 9 carbon atoms and optionally substituted by one, two, three or more alkyl radicals each containing from 1 to 4 carbon atoms, or, when n is 1, A and R together form an alkyl radical of from 4 to 7 carbon atoms or an alkenyl or alkynyl radical of from 4 to 9 carbon atoms, the imidazole being the free base or a pharmaceutically acceptable salt thereof. The 1-alkylimidazoles in which n is 0 and R ist cycloalkyl or cycloalkenyl are novel, as are those when A and R together form an alkenyl radical. Methods of preparing the 1-alkylimidazoles are disclosed. The 1-alkylimidazoles have pharmacological properties of use in medicine, in particular for the treatment or prophylaxis of thrombo-embolic disorders.

  Compounds of formula (I) having only two optically active centres, may exist as four isomers, each of which may be prepared by resolving a racemic amino-diester intermediate in the preparation thereof. The racemic amino-diester is selectively hydrolysed to the corresponding mono-ester which is acylated and subsequently selectively deacylated to produce the resolved mono-ester. Isomers of compounds of formula (I) having a particular configuration are biologically more active than the corresponding isomers having other configurations and are useful in medicine, either as the raw compound or in a pharmaceutical formulation, for example in inhibiting platelet aggregation.
