Abstract

The interaction of 6,7-dimethoxy-3-(3,4-dimethoxyphenyl)-2-benzopyrylium perchlorate with α-aminocarbonyl compounds forms N-α-aminocarbonyl-substituted isoquinolinium compounds which on treatment with acids are converted into dibenzo [a,g] quinolizinium compounds, one of which is the natural alkaloid dehydronorcoraldine. The products were characterized by the results of elementary analysis and IR, PMR, and UV spectroscopy.
