One-step synthesis of dipyrromethanes in water
Sobral, Abílio J. F. N.; Rebanda, Nuno G. C. L; Silva, Melo da; Lampreia, Sandra H.; Silva, M. Ramos; Beja, A. Matos; Paixão, J. A.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/...
