Synthesis of tetradehydrocorrins, corroles, and corrologens related to 12-decarboxyuroporphyrin III and uroporphyrin III
Abstract
The title compounds have been synthesized, for the first time, from the corresponding 1,19-dimetyl-, 1-methyl-19-iodo-, and 1,19-di-iodo-biladiene-ac derivatives respectively, by means of methods described earlier. The 1,19-di-iodobiladienes-ac could be cyclized, in the presence of sodium azide, to the corresponding 20-azaporphyrins.
