摘要：
Catechol-containing polymers have attracted much attention in recent years because of their versatile mussel-inspired adhesive function. We report herein the facile synthesis of 4-/3-substituted catechols using the Mannich reaction of catechol with formaldehyde and secondary amines. The reaction proceeds smoothly in water without any catalyst. Separation of the desired products is important for the success of this methodology, and was achieved by a pH-controlled solvent extraction and recrystallization process. The synthesized functional catech...
