Inverted sapphyrin: a new family of doubly N-confused expanded porphyrins

J Am Chem Soc. 2006 Oct 4;128(39):12640-1. doi: 10.1021/ja064675z.

Abstract

The synthesis of an inverted, methoxylated sapphyrin derivative is described. This system, wherein inversion of pyrrolic nitrogen atoms is configurationally enforced via the use of a 3,3'-bipyrrolic precursor, displays what is best described as "weak aromaticity" as judged from its spectroscopic features and supporting theoretical calculations.
