Reaction of 2-amino-3-(pyrrol-1-yl)-5,10,15-tris(4-tert-butylphenyl)corrolato copper(II) with arylaldehydes affords novel pi-extended beta,beta '-pyrrolo(1,2-a)pyrazino-fused corroles via a Pictet-Spengler reaction. Corrole shows an unprecedented reaction pathway, leading to a mixture of phenyl-substituted and nonsubstituted pyrrolopyrazino annulated species as reaction products.
