Synthesis and antimalarial activity of 94 novel bipyrrole tambjamines (TAs) and a library of B-ring functionalized tripyrrole prodiginines (PGs) against a panel of Plasmodium falciparum strains are described. The activity and structure–activity relationships demonstrate that the ring-C of PGs can be replaced by an alkylamine, providing for TAs with retained/enhanced potency. Furthermore, ring-B of

Asymmetric dimers of BODIPY dyes were synthesized from a,c-biladienes salts in good yields; this work constitutes a new versatile approach to the synthesis of BODIPY dyads, which display red-shifted absorptions and emissions in the visible spectral region, higher fluorescence quantum yields and larger Stokes shifts compared with monomeric BODIPYs. The X-ray structure of a 5,5’-dibromo-BODIPY dyad was

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.
