Synthesis of [1,2-A]-fused tricyclic dihydroquinolines by palladiumcatalyzed intramolecular C-N cross-coupling of polarized heterocyclic enamines

A simple methodology for [1,2-A]-fused tricyclic dihydroquinolines is established. The key ste of the methodology is an intramolecular Buchwald-Hartwig amination reaction of suitabl halogenated (both bromo and chloro) cyclic enaminoketones, enaminoesters and enaminonitrile with various ring size (from five-to seven-membered). Optimal reaction conditions (palladiu source, base, ligand) depend on the ring size of the starting enamine, giving 65-98% yield of th tricyclic product. A treatment of the products with perchloric acid gives respective quinoliniu perchlorates.

A new bicyclic oxazaborines with a bridged nitrogen atom, their thermic rearrangement and fluorescence properties

Cyclic β-enaminones bearing secondary amino group react with 4-substituted benzenediazonium tetraphenylborates in dichloromethane to form substituted bicyclic [1,3,2λ4]oxazaborines The oxazaborines rearrange, on heating to 200 °C in the absence of solvent or in DMF or DMSO, to isomeric 2H-[1,2,4,3λ4]triazaborines. Previously prepared [1,3,2λ4]oxazaborines derived from acyclic β-enaminones bearing secondary amino group either did not undergo the rearrangement or with a lot of difficulties and with negligible yield. The fluorescence behaviour of the prepared triazaborines was observed. These compounds fluoresce in 2-methyltetrahydrofurane and in solid state under low temperatures.

Acylation des β-enaminoesters: regio et stereoformation des β-enaminoesters N- ou C-acyles

The reaction of acyl chlorides with cyclic five-membered β-enaminoesters gave exclusively N-acylated products while reaction of acyl chlorides with cyclic seven-membered β-enaminoesters gave only C-acylated products.In the case of cyclic six-membered β-en
