Rearrangement of a 5,7-di-tert-butyl-2-(quinolin-2-yl)-1,3-tropolone into a pentalene derivative

Description

Acid-catalyzed rearrangement of 5,7-di-tert-butyl-2-(4-chloro-6,8-dimethylquinolin-2-yl)-1,3-tropolone leads to (R,S)-5-tert-butyl-2-(4-chloro-6,8-dimethyl-1H-quinolin-2-ylidene)-3,3,3a-trimethyl-3,3a-dihydropentalene-1,6(2H,6aH)-dione.The structure of the rearrangement product is established by 2D-correlation NMR and X-ray diffraction.The relative thermodynamic stability and tautomeric isomers of the new compound were evaluated by means of quantum chemical methods.A reaction mechanism is suggested.
