Skeletal Editing from Pyridine to Aniline via C‐Insertion and N‐Isomerization
ChemistryEurope, EarlyView.A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta‐primary aniline products. A key carbene‐insertion step precedes nitrogen migration, preserving both ring size and overall structure.

Biosynthesis of Isoquinoline Alkaloids [PDF]
Planta Medica, 1979 The isoquinoline alkaloids and their biosynthetic relatives include many compounds which show important physiological properties in animals: dopamine, mescaline, morphine, papaverine, and narcotine are pertinent examples. The biosynthetic routes to the members of this family start from the essential aminoacids tyrosine or phenylalanine. Decarboxylation
