Abstract
The first stepwise syntheses of unsymmetrically substituted 1,19-dibromo-a,c-biladienes, e.g. 3c, via the so-called 'tripyrrene route', and their facile conversion into biliverdins (bilin-1,19-diones), e.g. 4c, are described; this methodology is also adapted for the preparation of symmetrical biliverdins 4a, as well as corroles 5 and azaporphyrins 6.
