Ring Syntheses of the Four N-Methylprotoporphyrin Isomers and of Related N-Methyl and N,N'-Dimethylporphyrins

Pandey, Ravindra K.,Jackson, Anthony H.,Smith, Kevin M.

, p. 1211 - 1220 (2007/10/02)

Total syntheses of the four isomeric N-methylprotoporphyrin IX dimethyl esters have been achieved by the MacDonald and tripyrrene/a,c-biladiene routes using appropriate N-methylpyrroles and N-methyldipyrromethanes as intermediates.The syntheses of related N-methyl and N,N'-dimethylporphyrins have also been achieved by the MacDonald route.
