<p>The invention relates to new ethenylimidazoles of the formula <CHEM> in which n is 0, 1 or 2, R1 represents a halogen atom, a trifluoromethyl group or an alkyl or alkoxy group with at most 6 carbon atoms, the two substituents being the same or different when n is 2, R2 represents an alkyl group with 1 to 6 carbon atoms, an alkenyl group with 2 to 4 carbon atoms or a cycloalkyl group with 3 to 6 carbon atoms, R3 represents a hydrogen atom, an alkyl group with 1 to 6 carbon atoms or an alkenyl group with 2 to 4 carbon atoms and R4 represents a hydrogen atom, an alkyl group with 1 to 6 carbon atoms or a nitro group, and their acid addition salts. Other features of the invention are - processes for the preparation of compounds of formula I, - pharmaceutical compositions comprising a compound of formula I, - novel phosphine oxides of the formula <CHEM> in which R5 and R6 are the same or different and each represents an unsubstituted or substituted phenyl group and R3 and R4 are as defined above, - a process for the preparation of phosphine oxides of formula XI.</p> |
