(a) Detection and synthesis. While revisiting our recent 'near-instantaneous' synthesis of isocorroles via the DDQ-mediated oxidative coupling of pyrrole to corrole, we noticed a red fraction remaining on the column after column-chromatographic isolation of the isocorrole. Mass spectrometry indicated a molecular formula consistent with 'corrole + 2pyrrole -2H', suggesting oxidative addition of a second molecule of pyrrole to the initially formed pyrrole-appended isocorrole, a surmise that 1 H NMR spectroscopy would later confirm. We named the new product calixcorrole by analogy with calixphyrin.
