Composition consisting of a mixture of (E) and (Z) isomers of esters of general formula: STR1 in which R represents a C1 -C4 alkyl radical, containing at least 85% of (E) isomer. A process for preparing such a composition. The use of such a composition for preparing (E)-2-propyl-2-pentenoic acid of formula: STR2 and also its pharmaceutically acceptable salts.

2-14C Labelled 5-alkyluracils were prepared by condensation of the diethylacetals of α-formyl-carbonic acid esters with 14C-thiourea. Compounds labelled at 4-C were synthesized by condensation of the labelled carboxylic acid derivatives with thiourea. β-Anomers of 5-alkyl-2'-deoxyuridines were obtained in a fairly good radiochemical yield. Alkyl substituents ranged from methyl to tetradecyl, isopropyl and tert-butyl.
