synthesized in reasonable yields from benzonitriles having an amide moiety at the ortho-position, via the sequential (i) In-mediated allylation of nitrile moiety to form an imine intermediate, (ii) intramolecular quenching of an acyl group by the imine intermediate, and (iii) a proton transfer to dienamide.

[EN] Compounds of formula (I), in which R1 and R2 are independently a substituted phenyl group, where the substituents are as defined in the claims and with the proviso that at least one of the substituents is a cyano, carboxy or (C1-4)alkoxycarbonyl group, are inhibitors of CCR9 activity useful for therapeutic treatment, particularly of irritable bowel disease. [FR] La présente invention concerne des composés de formule (I) dans laquelle R1 et R2 représentent indépendamment un groupe phényle substitué. Les substituants sont tels que définis dans les revendications de la présente invention, sous réserve qu'au moins un des substituants soit un groupe cyano, carboxy ou (C1-4)alkoxycarbonyle. Ces composés constituent des inhibiteurs de l'activité du récepteur CCR9 utilisés dans le cadre d'une thérapie, en particulier pour traiter le syndrome du côlon irritable.
Palladium(II)-Catalyzed Cyclization Reaction of 2-(Alk-2′-ynyl- oxy)benzonitriles or 2-(Alk-2′-ynylamino)benzonitriles: A Facile Way to 2<i>H</i>-Chromene and 1,2-Dihydroquinoline Derivatives

2-dihydroquinolines from palladium(II)-catalyzed tandem reactions of 2-(alk-2′-ynyloxy)benzonitriles or 2-(alk-2′-ynylamino)benzonitriles was developed. This tandem reaction involves an intermolecular trans-acetoxypalladation of an alkyne followed by an addition to the nitrile group to quench the carbon-palladium bond and complete the catalytic cycle without the necessity of a redoxsystem.
