Synthese polycyclischer Azulene

Abstract: Kondensdtion von 6-Dimethylamino-2-(dimethyliminiomethyl)fulven-perchlorat (2) mil aciden DreikohlenstoRkomponenten, wie z. B. Glutaconslure-dilthylester (3c), fiihrt zu tieffdrbigen Polyenaminen, die beim Erwlrmen unter Dimethylamin-Abspaltung zu im Siebenring substituierten Azulenen 5 cyclisieren. Analog erhalt man aus 2 mit 2-Methylchromon, I-Acenaphthenon und Fluoren die polycyclischen Verbindungen 7. 8 und 11. Ein zu 11 isomerer, azulenoider Kohlenwasserstoff 15a wurde nach einer ZiegSler-Hufner-Synthese … Show more

“…The electronic spectrum of ketone 14 in 10% H,SO, is very similar to that of 2. This finding indicates that 14 is also protonated at the nitrogen atom rather than on the carbonyl oxygen, giving a cation analogous to 16 (i.e. cation 18).…”

“…[17] The availability of the diester 11 was very promising, as one of the most convenient methods for macrocyclization involved aminolysis of diesters with a,w-diamines. Unfortunately though, the ester 11 was unreactive under standard conditions, and we succeeded in preparation of the desired amide 5 a only by performing the reaction in neat butylamine.…”
