Synthesis of 5-(4-Acetamidophenyl)-10,15,20-tris(4-Substituted Phenyl) Porphyrins using Dipyrromethanes
摘要:
A convenient procedure for the synthesis of 5-(4-acetamidophenyl)-10,15,20-tris(4-substituted phenyl) porphyrins (5-8) from dipyrromethane is reported. meso-(4-Substituted phenyl) dipyrromethanes (1-4) were obtained in yields of 72-84% by the reaction of 4-substituted benzaldehyde with an excess of pyrrole. The porphyrins (5-8) were isolated with appreciable yields of 15-17%.
