摘要

Treatment of N-carbethoxy-1-benzylideneisoquinolines with LDA gives N-ethoxycarbonyl-1- amino-1-(2-vinylphenyl)-2-phenylethylenes, which can easily be transformed into N- carbethoxy-1-amino-2-phenylnaphthalenes. Bischler–Napieralski reaction of these latter compounds affords the corresponding benzo [c] phenanthridines, while their hydrolysis and subsequent oxidation constitutes a novel route to 2-phenyl-1, 4-naphthoquinones.
