New N-Substituted (E)-4-Arylidene Isoquinoline-1,3-dione Derivatives: NMR Spectroscopic Investigation and Antibacterial Activity
摘要:
New N-substituted 4-arylidene-isoquinoline-1,3-dione derivatives were obtained as one geometrical isomer by aldol condensation of the appropriate aldehyde and the corresponding N-substituted homophthalimides. The structural elucidation of compounds 3a-h was established by infrared and NMR spectroscopy including H-1, C-13, CH CORR, and distortionless enhancement by polarization transfer measurements. Compounds 3d-h were evaluated for their antibacterial activity against some strains of bacteria using the disc diffusion method and microdilution tests.
