✦ Synopsis

7a)["l). The conjugative stabilization accompanying the formation of the pyrromethenic partial structure in the C,Dring region presumably promotes an eventual didehydrogenation step["' to (6). The same partial structure also occurs in the hexahydroporphinoid ligand system (1).

The transformation (5) + (6) is another experimental variant of Johnson's synthesis of corrinoid structures from tetrapyrrolic
