摘要:
The synthesis of novel N- substituted 5,5-dimethyl-2,5-dihydro-4H-isoindol-4-ones by reaction of 5,5-dimethyl-2,5-dihydro-4H-isoindol-4-one (1) with appropriate electrophiles (methyl iodide, 3,3-dimethylallyl bromide, 2-N,N-dimethylethyl chloride, ethyl 3-bromopropionate, benzoyl chloride, N,N-dimethyl-chloroformate, phenyl chloroformate) is described. Moreover, detailed nmr spectroscopic studies (H-1, C-13) with the title compounds are presented.
