1-arylmethyl-1,2,3,4-tetrahydro-2,2-dimethylisoquinolinium iodides with methanolic KOH gave stilbene derivatives, for example, (E)-N-22-[2-(phenyl)ethenyl]-4,5-dimethoxyphenyl}ethyl-N,N-dimethylamine. Photochemical electrocyclization of these stilbenes afforded the corresponding phenanthrene alkaloids/phenanthrene derivatives.
霍夫曼用甲醇KOH降解1-芳基甲基1,2,3,4-四氢-2,2-二甲基异喹啉碘化物,得到二苯乙烯衍生物,例如(E)-N -2 2- [2-(2-苯基)乙烯基] ] -4,5-二甲氧基苯基}乙基-N,N-二甲基胺。这些苯乙烯的光化学电环化得到相应的菲生物碱/菲衍生物。
