MICROWAVES ASSSITED CYCLOADITION REACTIONS OF UNSATURATED PHENOTHIAZINE DERIVATIVES. Authors: EMESE GÁL, LUIZA GĂINĂ, CASTELIA CRISTEA, LUMINIŢA SILAGHI-DUMITRESCU. |

Abstract: Microwaves assisted azaDiels-Alder cycloaddition reactions using aromatic and heteroaromatic Schiff bases as heterodienes and 3,4-dihydro-2H-pyrane (DHP) as dienophyle in the presence of iodine catalyst, afforded stable cycloaddition adducts, as well as their oxidation products. The structures of the new hexahydro-2H-pyrano[3,2-c]quinoline and 3-(3-hydroxypropyl)-quinoline derivatives were assigned based on spectroscopic methods (high resolution NMR and mass spectrometry). Keywords: Phenothiazine, Ferrocene, aza-Diels-Alder cycloaddition, Schiff base, 3,4-dihydro-2H-pyrane. |
