Abstract

Novel 2,3,4,9-tetrahydro- and 4,9-dihydro-1H-benzo[f]isoindole derivatives were synthesized from Juglone and amino-acid azomethines in 74–85% yields via 1,3-dipolar cycloaddition. The stereo- and regioselectivity of cycloaddition was confirmed by NMR spectra and single-crystal X-ray diffraction analysis.
