[EN] HETEROCYCLIC COMPOUNDS FOR MEDIATING TYROSINE KINASE 2 ACTIVITY [FR] COMPOSÉS HÉTÉROCYCLIQUES POUR LA MÉDIATION DE L'ACTIVITÉ DE LA TYROSINE KINASE 2
A mild and reproducible method for the formation of a nonstabilized azomethine ylide was developed by photoinduced reaction catalyzed with eosin Y under green light irradiation. Resulting 1,3-dipole was trapped with fluoroalkenes, fluoroalkylated alkenes, and representative dipolarophiles to access pyrrolidine scaffolds, including spirocyclic compounds. The mechanism involved in this transformation
Compounds of formula (I) wherein: A is Formula (II), Formula (III), or Formula (IV) and B is Formula (V), Formula (VI), or Formula (VII), can be used in a variety of applications including use as antibacterial agents.

Upon sonication with lithium fluoride in acetonitrile N-benzyl-N-methoxymethyl(trimethylsilylmethyl)amines 9a–c undergo chemoselective 1,3-dipolar cycloaddition with 4-vinylfuranones 2 and 6 to afford pyrrolidinylfuranones 10, 11a–c and 12a–c. The stereochemistry is assigned by X-ray analyses and proton NMR data comparison of related oxiranylfuranone 13.
