Chinazolinderivate durch Cyclodehydrierung von N-(2-substituierten Aryl)-Piperidinen

3.2 Enhancement above the Arabian Sea and India Three days backward trajectories were calculated for both flight tracks of outward and return flight over the Arabian Sea.. The

Suzuki-Miyaura reaction of cyclic vinyl boronates, derived from the vinyl triflates of N -protected tetrahydropyridines, with appropriate aryl halides yielded 4-aryl- piperidines.

Key words: Crystal Structures, Infrared Spectra, Inverse 12-Metallacrown Complexes, Methyl(2-pyridyl)ketone Oxime Complexes, Zinc(II)

Complexes 1 and 2 join a small family of struc- turally characterized metal complexes containing the neutral or the anionic forms of methyl 2-pyridyl ke- tone oxime as ligands..

Die Oxidation von 1a – c mit Quecksilber(II)- ethylendiamintetraacetat [Hg(II)-EDTA] ergab ¨uberra- schenderweise die Lactame 3a – c, was eine doppelte Dehydrierung erfordert,

The chemical shifts of both the aro- matic protons and the aromatic carbons of all the amides are calculated in two ways, either by adding the incremental shifts due to -COCH 3 − i X
