(EN) The present invention provides a novel imidazole derivative having chemical formula (I). These compounds are useful for preventing or treating hypertension or congestive heart failure and have high activity, rapid action upon intravenous injection, good oral absorbtion, low toxicity, and long-lasting action. Also provided are pharmaceutical compositions which contain these compounds.(FR) La présente invention se rapporte à un nouveau dérivé d'imidazole répondant à la formule chimique (I). Ces composés peuvent être utilisés pour prévenir ou traiter l'hypertension artérielle ou l'insuffisance cardiaque, et font preuve d'un effet rapide à forte activité lorsqu'ils sont administrés par injection intraveineuse, ainsi que d'une bonne absorption par voie orale, d'une faible toxicité et d'une action prolongée. On décrit également des compositions pharmaceutiques contenant ces composés.
Synthesis of conjugated dienes <i>via</i> palladium-catalysed aerobic dehydrogenation of unsaturated acids and amides
A Pd(II)-catalyzed direct aerobic dehydrogenation of γ,δ-olefinic acids and amides has been demonstrated. The present protocol dehydrogenates the least acidic amides and acids, thus replacing the traditional enolate strategy for dehydrogenation. A broad spectrum of conjugated dienamides and dienoic acids were produced in good to excellent yields. A possible reaction mechanism was proposed and supported
