A short synthetic route to asymmetric iridoids was developed. The three key steps were an intramolecular [4 + 2] cycloaddition reaction of an enamine derivative of 8-oxocitral (2), a dynamic acetylation, and an enzymatic resolution of the gastrolactyl acetates 5a and 5b, iridoids with three stereocenters. Some regio- and stereoselective heterogeneous catalytic hydrogenations of double bonds in iridoid

The invention relates to novel soothing compositions for animals, particularly for cats. It specifically relates to soothing compositions for non-human mammals, comprising between 1% and 50% w/w of at least one fatty acid comprising between 5 and 22 carbon atoms and between 0.01% and 5% w/w of nepetalactone, such that said at least one fatty acid and said nepetalactone are dissolved in a solvent. Said compositions are characterised in that they exhibit soothing properties for stressed animals and are stable for the entire period of use thereof.

La présente invention concerne de nouvelles compositions apaisantes pour animaux, en particulier les chats, elle vise plus particulièrement des compositions apaisantes pour mammifères non humain comprenant entre 1 % et 50% en poids/poids d'au moins un acide gras comprenant entre 5 et 22 atomes de carbone et entre 0,01% et 5% en poids/poids de népétalactone, telles que le(s)dit(s) acide(s) gras et ladite népétalactone sont en solution dans un solvant. Ces compositions ont la particularité de présenter des propriétés apaisantes pour l'animal dans le cas de stress et sont stables pendant toute la durée de leur utilisation.
