What is Synthesis of Lawsone Pigments via Mannich Reaction about?
The document presents a one-pot protocol for synthesizing Lawsone family pigments using a three-component Mannich reaction with Carboxymethyl Cellulose (CMC) as a catalyst under ball milling conditions. This method is efficient, environmentally friendly, and results in high yields of 2-hydroxy-1,4-naphthoquinone derivatives without the use of solvents. The study highlights the advantages of using CMC, including its low cost, biodegradability, and reusability as a catalyst.
