A practical and sustainable protocol for the clean preparation of various multisubstituted pyrroles through an iodine-catalyzed multicomponent reaction under metal- and solvent-freeconditions was developed. In the gram-scale synthesis, the desired pyrroles can be easily isolated in high-purity through simple extraction.

N-disubstituted formamide, has been developed to give a series of multisubstituted pyrroles in moderate to good yields with high regioselectivities. This reaction not only reveals a new reaction mode for α-aminonitriles, but also provides a new and efficient cyclization pattern for the synthesis of multisubstituted pyrroles as well as their derivatives, which might facilitate related biological studies
