Novel norcaradiene-cycloheptatriene systems fused with arylisoxazoles were synthesized and their temperature dependent 1H nmr spectra were studied. while the fusion of isoxazole ring much shifted the norcaradiene-cycloheptatriene equilibrium to the side of norcaradiene form, the rapid isomerizations of the norcaradienes with their enantiomers were observed and their δG‡c values were obtained.
