dimethoxymethyl, oxo, methoxy, methylthio, iminomethyl, ethoxycarbonylvinyl, dicyanovinyl) substituents have been prepared and examined in the directed synthesis of bacteriochlorins. The routes – inspired by a directed route to chlorins – rely on condensation of two hydrodipyrrins to produce a hydrobilin followed by ring closure to form the macrocycle. Four new unsymmetrically substituted bacteriochlorins

conditions has afforded diverse bacteriochlorins (e.g., bearing alkyl/ester, aryl/ester, diester, and no substituents) in a few days from commercially available starting materials. Consideration of the synthetic steps and yields for formation of the dihydrodipyrrin-acetal and bacteriochlorin underpins evaluation of synthetic plans for early installation of bacteriochlorin substituents via the dihydrodipyrrin-acetal
