Abstract
U ovome radu prikazana je priprava 3,3-diarilizoindolin-1-ona modificiranom enantioselektivnom Bettijevom reakcijom: asimetričnom organokatalitičkom adicijom fenola na in situ generirane N-acil diarilketimine kataliziranom kiralnom fosfornom kiselinom. Kao stabilni prekursori N-acil diarilketimina korišteni su 3-aril-3-hidroksiizoindolin-1-oni pripravljeni adicijom Grignardovih reagensa i organolitijevih spojeva na ftalimid. Provedene su priprave racemičnih 3,3-diarilizoindolin-1-ona u svrhu potvrde reaktivnosti ovakvih spojeva u modificiranoj Bettijevoj reakciji. Istraženi su utjecaji halogeniranih arilnih skupina i heterocikličkih skupina na položaju 3 izoindolinona na enantioselektivnost i prinos reakcije.Strukture priređenih spojeva potvrđene su 1H i 13C NMR spektroskopijom te spektrometrijom masa dok je stupanj enantioselektivnosti određen tekućinskom kromatografijom visoke djelotvornosti s kiralnom kolonom.
Abstract (english)
An approach to enantioenriched 3,3-diaryl isoindolin-1-ones was developed using the asymmetric chiral phosphoric acid-catalyzed addition of phenols to in situ generated N-acyl diarylketimines. 3-aryl-3-hydroxyisoindolin-1-ones were prepared as stable precursors of the reactive N-acyl diarylketimines by the addition of Grignard reagents and organolithium compounds to phtalimide. The influence of the aryl group on the reaction outcome was studied. 3-aryl 3-hydroxyisoindolin-1-ones are precursors in the synthesis of chiral - triarylmethylamines. The structures of prepared compounds were confirmed by 1H and 13C NMR spectroscopy, as well as mass spectrometry. The enantioselectivity in the products was determined by chiral HPLC.
