The rapid and facile synthesis of highly substituted β-iodofurans and β-iodopyrroles is reported using a mixture of molecular iodine and a base in solid PEG 3400 as alternative, eco-friendly and nontoxic solvent under microwave irradiation, in a very short time. The heterocycles are efficiently recovered in good yields by a simple workup procedure, avoiding chromatographic purification.

Abstract
The rapid and facile synthesis of highly substituted β-iodofurans and β-iodopyrroles is reported using a mixture of molecular iodine and a base in solid PEG 3400 as alternative, eco-friendly and nontoxic solvent under microwave irradiation, in a very short time. The heterocycles are efficiently recovered in good yields by a simple workup procedure, avoiding chromatographic purification.File in questo prodotto:
