✦ Synopsis
A highly symmetrical doubly fused porphyrin was obtained after two successive intramolecular cyclizations. [1] The first supplementary ring was closed by using the Cadogan reaction, involving the generation of an intermediate nitrene from the starting nitro function. By trying to use the same methodology for the second ring closure, we found that the Cadogan reaction could be used but that cyclization yields remained low. We showed, by taking into account unusual
