Description

In this communication we describe the first results of an efficient synthesis of [beta]-free-dipyrromethanes in water. This new method affords very pure products in moderate to high yields, using a cheap, non-toxic, environment friendly solvent, in a one-step procedure from pyrrole and carbonyl compounds, needing little or no work up procedures. http://www.sciencedirect.com/science/article/B6THS-48FBYP9-W/1/58e27991754d6f7646fd28ad555927b4
