dc.description.abstract | Reakce anilů kafru, N-((1R,4R)-1,7,7-trimethylbicyklo[2.2.1]heptan-2-yliden)benzenaminu a N-(1,7,7-trimethylbicyklo[2.2.1]heptan-2-yliden)benzenaminu, s magickými malonáty (bis(2,4,6-trichlorfenyl)-2-butyl- a bis(2,4,6-trichlorfenyl)-2-fenylmalonát) vede ke 4-hydroxy-2(1H)-pyridonům připojeným k bornanovému cyklickému systému (např. (5S,8R)-3-butyl-5,6,7,8-tetrahydro-4-hydroxy-8,9,9-trimethyl-1-fenyl-5,8-methanochinolin-2(1H)-on) s dobrými výtěžky. Méně uspokojivé výtěžky byly dosaženy s diethyl-2-fenylmalonátem. Reakce přebytku diethyl-malonátu s N-(1,7,7-trimethylbicyklo[2.2.1]heptan-2-yliden)benzenaminem poskytuje pyronoderivát 4-hydroxy-7,11,11-trimethyl-6-fenyl-7,8,9,10-tetrahydro-7,10-methano-2H-pyrano[3,2-c]chinolin-2,5(6H)-dion, který lze snadno odbourat přes jeho acetylderivát 3-acetyl-4-hydroxy-8,9,9-trimethyl-1-fenyl-5,6,7,8-tetrahydro-5,8-methanochinolin-2(1H)-on na základní sloučeninu se structurou 4-hydroxy-8,9,9-trimethyl-1-fenyl-5,6,7,8-tetrahydro-5,8-methanochinolin-2(1H)-on. | cs |
dc.description.abstract | The reaction of camphoranils N-((1R,4R)-1,7,7-trimethylbicyclo[2.2.1]heptan-2-ylidene)benzenamine and N-(1,7,7-trimethylbicyclo[2.2.1]heptan-2-ylidene)benzenamine with magic malonates (bis(2,4,6-trichlorophenyl) 2-butyl- and 2-phenylmalonates) leads to 4-hydroxy-2(1H)-pyridones attached to bornane ring system (e.g. (5S,8R)-3-butyl-5,6,7,8-tetrahydro-4-hydroxy-8,9,9-trimethyl-1-phenyl-5,8-methanoquinolin-2(1H)-one) in good yields. Less satisfactory yields were obtained with the di-Et 2-phenylmalonate. The reaction of an excess of di-Et malonate with N-(1,7,7-trimethylbicyclo[2.2.1]heptan-2-ylidene)benzenamine yields the pyrono deriv. 4-hydroxy-7,11,11-trimethyl-6-phenyl-7,8,9,10-tetrahydro-7,10-methano-2H-pyrano[3,2-c]quinoline-2,5(6H)-dione, which can readily be degraded via the acetyl deriv. 3-acetyl-4-hydroxy-8,9,9-trimethyl-1-phenyl-5,6,7,8-tetrahydro-5,8-methanoquinolin-2(1H)-one to the basic structure 4-hydroxy-8,9,9-trimethyl-1-phenyl-5,6,7,8-tetrahydro-5,8-methanoquinolin-2(1H)-one. | en |
