Abstract
The dimethyl esters of protoporphyrin IX and pemtoporphyrin were synthesized by cyclization ofa,c-biladienes to the corresponding porphyrins, which containβ -diethylaminoethyl groups as potential vinyl substituents, and subsequent Hofmann degradation of them to vinylporphyrins in high yields.
