The dipyrromethanecarbinol motif is a key component in rational routes to a wide variety of porphyrinic macrocycles. We have investigated the dipyrromethane-monocarbinol self-condensation and the dipyrromethane-dicarbinol + dipyrromethane condensation under four different acid-catalysis conditions and have characterized the oligomer composition (by LD-MS), yield of porphyrin (by UV–Vis), and yield of N-confused porphyrin (by HPLC). Under conditions giving “no-scrambling”, the condensations are… CONTINUE READING
